Introduction
Introduction to the Binary Pump

Introduction to the Binary Pump
The binary pump comprises two identical pumps integrated into one housing. It provides gradient generation by high-pressure mixing. Degassing is not included but a vacuum degasser is available as a separate product for applications that require best flow stability especially at low flow rates or maximum detector sensitivity. This is most likely required to run small internal diameter columns (2 mm and 1 mm i.d.) which require low flow rates. A solvent selection valve (optional) will allow to select a binary mixture (isocratic and gradient) from four independent solvent bottles. An active seal wash (optional) is available when the pump is used with concentrated buffer solutions.

Overview of the Binary Pump
Overview of the Binary Pump
The binary pump is based on a two-channel, dual-piston in-series design which comprises all essential functions that a solvent delivery system has to fulfill. Metering of solvent and delivery to the high-pressure side are performed by two pump assemblies which can generate pressure up to 400 bar.
Each channel comprises a pump assembly including pump drive, pump head, active inlet valve which has a replaceable cartridge, and outlet valve. Both channels are connected in a low-volume mixing chamber which is connected by a capillary coil to a damping unit and a mixer. A purge valve including a PTFE frit is fitted at the pump outlet for convenient priming of the pumping system.
A seal wash (optional) is available when the pump is used with buffer solutions.

The liquid runs from the solvent reservoir through an active inlet valve. Each side of the binary pump comprises two substantially identical pump units. Both pump units comprise a ball-screw drive and a pump head with two sapphire pistons for reciprocating movement.
Idb m c X]VbWZg Bdidgl i]ZcXdYZg Principle of Pump Unit 1260 Binary Pump VL User Manual
Introduction
Overview of the Binary Pump

A servo-controlled variable reluctance motor drives the two ball-screw drives in opposite directions. The gears for the ball-screw drives have different circumferences (ratio 2:1) allowing the first piston to move at double the speed of the second piston. The solvent enters the pump heads close to the bottom limit and leaves it at its top. The outer diameter of the piston is smaller than the inner diameter of the pump-head chamber allowing the solvent to fill the gap in between. The first piston has a stroke volume in the range of 20 µL to 100 µL depending on the flow rate. The microprocessor controls all flow rates in a range of 1 µL/min to 5 mL/min. The inlet of the first pumping unit is connected to the active inlet valve which is processor-controlled opened or closed allowing solvent to be drawn into the first pump unit.
The outlet of the pump unit is connected directly to the second pump unit. The outlet of the second pump unit is connected via a small mixing chamber, a coil and the damping unit to the purge valve assembly. The outlet of the purge valve assembly is then connected to the following chromatographic system.
When turned on, the pump runs through an initialization procedure to determine the upper dead-center of the first piston of both pump channels. The first piston moves slowly upwards to the mechanical stop of the pump head and from there it moves back a predetermined path length. The controller stores this piston position in memory. After this initialization the pump starts operation with the set parameters for the two pump channels.
The active inlet valve is opened and the down moving piston draws solvent into the first pump head. At the same time the second piston is moving upwards delivering into the system. After a controller-defined stroke length (depending on the flow rate) the drive motors are stopped and the active inlet valve is closed. The motor direction is reversed and moves the first piston up until it reaches the stored upper limit and at the same time moving the second piston downwards.
Then the sequence starts again moving the pistons up and down between the two limits. During the upward movement of the first piston the solvent in the pump head is pressed through the outlet ball valve into the second pumping unit. The second piston draws in half of the volume displaced by the first piston and the remaining half volume is directly delivered into the system. During the drawing stroke of the first piston, the second piston delivers the drawn volume into the system.

The compressibility of the solvents in use will affect retention-time stability when the back pressure in the system changes (for example, ageing of column). In order to minimize this effect, the pump provides a compressibility compensation feature which optimizes the flow stability according to the solvent type. The compressibility compensation is set to a default value and can be changed through the user interface.
Without a compressibility compensation the following will happen during a stroke of the first piston. The pressure in the piston chamber increases and the volume in the chamber will be compressed depending on backpressure and solvent type. The volume displaced into the system will be reduced by the compressed volume.
With a compressibility value set the processor calculates a compensation volume, that is depending on the backpressure in the system and the selected compressibility. This compensation volume will be added to the normal stroke volume and compensates the previous described loss of volume during the delivery stroke of the first piston.
1260 Binary Pump VL User Manual
Introduction
Overview of the Binary Pump

How Does Variable Stroke Volume Work?
Due to the compression of the pump-chamber volume each piston stroke of the pump will generate a small pressure pulsation, influencing the flow stability of the pump. The amplitude of the pressure pulsation depends mainly on the stroke volume and the compressibility compensation for the solvent in use. Small stroke volumes generate pressure pulsations of smaller amplitude than higher stroke volumes at the same flow rate. In addition, the frequency of the pressure pulsations is higher. This decreases the influence of flow pulsations on quantitative results.
In gradient mode smaller stroke volumes result in a lower flow ripple improve composition ripple.
The module uses a processor-controlled spindle system for driving its pistons. The normal stroke volume is optimized for the selected flow rate. Small flow rates use a small stroke volume while higher flow rates use a higher stroke volume.
By default, the stroke volume for the pump is set to AUTO mode. This means that the stroke is optimized for the flow rate in use. A change to larger stroke volumes is possible but not recommended.
1260 Binary Pump VL User Manual
Early Maintenance Feedback
Early Maintenance Feedback
Maintenance requires the exchange of components which are subject to wear
or stress. Ideally, the frequency at which components are exchanged should be
based on the intensity of usage of the module and the analytical conditions,
and not on a predefined time interval. The early maintenance feedback (EMF)
feature monitors the usage of specific components in the instrument, and
provides feedback when the user-selectable limits have been exceeded. The
visual feedback in the user interface provides an indication that maintenance
procedures should be scheduled.
EMF Counters
EMF counters increment with use and can be assigned a maximum limit which
provides visual feedback in the user interface when the limit is exceeded.
Some counters can be reset to zero after the required maintenance procedure.
Using the EMF Counters
The user-settable EMF limits for the EMF Counters enable the early maintenance
feedback to be adapted to specific user requirements. The useful maintenance
cycle is dependent on the requirements for use. Therefore, the definition of the
maximum limits need to be determined based on the specific operating
conditions of the instrument.
Setting the EMF Limits
The setting of the EMF limits must be optimized over one or two maintenance
cycles. Initially the default EMF limits should be set. When instrument
performance indicates maintenance is necessary, take note of the values
displayed by the EMF counters. Enter these values (or values slightly less than
the displayed values) as EMF limits, and then reset the EMF counters to zero.
The next time the EMF counters exceed the new EMF limits, the EMF flag will be
displayed, providing a reminder that maintenance needs to be scheduled.
1260 Binary Pump VL User Manual
The industrial design of the module incorporates several innovative features. It uses Agilent's E-PAC concept for the packaging of electronics and mechanical assemblies. This concept is based upon the use of expanded polypropylene (EPP) layers of foam plastic spacers in which the mechanical and electronic boards components of the module are placed. This pack is then housed in a metal inner cabinet which is enclosed by a plastic external cabinet. The advantages of this packaging technology are: virtual elimination of fixing screws, bolts or ties, reducing the number of
components and increasing the speed of assembly/disassembly, the plastic layers have air channels molded into them so that cooling air can
be guided exactly to the required locations, the plastic layers help cushion the electronic and mechanical parts from
physical shock, and the metal inner cabinet shields the internal electronics from
electromagnetic interference and also helps to reduce or eliminate radio frequency emissions from the instrument itself.

Priming the System

Priming the System
Before a degasser or solvent tubing can be used, it is necessary to prime the system. Isopropanol is recommended as priming solvent due to its miscibility with nearly all HPLC solvents and its excellent wetting properties.
Connect all modules hydraulically as described in the respective module manuals.
Fill each solvent bottle with 100 mL isopropanol Switch the system on When opening capillary or tube fittings, solvents may leak out.
The handling of toxic and hazardous solvents and reagents can carry health risks.
➔ Observe appropriate safety procedures (for example, wear goggles, safety gloves and protective clothing) as described in the material handling and safety data sheet supplied by the solvent vendor, especially when toxic or hazardous solvents are used.
The purge tool of the LabAdvisor or Instrument Utilities can be used to purge the pump If the pump is not able to draw in the solvent from the bottles, use a syringe to move the solvent manually through tubing and degasser.
1260 Binary Pump VL User Manual
Installing the Pump
Priming the System
When priming the vacuum degasser with a syringe, the solvent is drawn through the degasser tubes very quickly. The solvent at the degasser outlet will therefore not be fully degassed. Pump for approximately 10 minutes at your desired flow rate before starting an analysis. This will allow the vacuum degasser to properly degas the solvent in the degasser tubes.
1 Open the purge valve of the pump
2 Set the flow rate to 5 mL/min.
3 Select channel A1
4 Turn the flow on
5 Observe if the solvent in the tubing of channel A1 is advancing towards the
pump. If it isn't, disconnect the solvent tubing from the solvent selection valve, attach a syringe with a syringe adapter and pull the liquid through the degasser. Reattach the tubing to the solvent selection valve.
6 Pump 30 mL isopropanol to remove residual air bubbles.
7 Switch to the next solvent channel and repeat steps 5 and 6 until all
channels have been purged.
8 Turn the flow off and close the purge valve.

When the pumping system has been turned off for a certain time (for example, overnight) air will rediffuse into the solvent channel between the vacuum degasser and the pump. If solvents containing volatile components are left in the degasser without flow for a prolonged period, there will be a slight loss of the volatile components.

Hints for Successful Use of the Binary Pump

Hints for Successful Use of the Binary Pump
Place solvent cabinet with the solvent bottles always on top (or at a higher
level) of the pump.
When using the binary pump without vacuum degasser, shortly degas your solvents by putting the solvent to a suitable container and applying a vacuum pressure for some time. If possible apply solvent conditions that will decrease the gas solubility over time (for example, warming up the solvents).
The use of a vacuum degasser is mandatory for flow rates below
0.5 mL/min and for configurations without damper and mixer.
When using the binary pump with vacuum degasser, flush the degasser with
at least 5 mL per channel before operating the pump, especially when the pumping system had been turned off for a certain length of time (for example, overnight) and volatile solvent mixtures are used in the channels (see Prevent blocking of solvent inlet filters (never use the pump without solvent
inlet filters). Growth of algae should be avoided (see Check purge valve frit and column frit in regular time intervals. A blocked
purge valve frit can be identified by black, yellow or greenish layers on its surface or by a pressure greater than 10 bar in low delay volume configuration and 20 bar in standard configuration when pumping distilled water at a rate of 5 mL/min with an open purge valve.
Whenever possible use a minimum flow rate of 5 µL/min per solvent
channel to avoid crossflow of solvent into the unused pump channel.
Whenever exchanging the pump seals, the purge valve frit should be
exchanged, too.
When using buffer solutions, flush the system with water before switching it
off. The seal wash option should be used when buffer solutions with concentrations of 0.1 M or higher are being pumped for long periods of time.
Check the pump pistons for scratches, grooves and dents when changing
the piston seals. Damaged pistons cause micro leaks and will decrease the lifetime of the seals.
After changing the piston seals, apply the seal wear-in procedure (s

Pump Control
The pump can be switched between following states: On, Off or to Standby. In
Standby, the pump motor is still controlled. When the pump is switched on
from standby, it does not re-initialize.
Upon initialization, the pump ignores the Maximum Flow Gradient value. This can result in a rapid and uncontrolled pressure increase. ➔ To prevent harm to the column, open the purge valve until the initialization is The optional seal wash pump can be controlled by either switching it off, using it for a single time or specifying frequency and duration of periodic wash intervals.

The pump offers a powerful feature to monitor the liquid level in the solvent bottles. With total bottle volume and initial filling volume set correctly, the pump subtracts the consumed volume continuously from the initial value and stops the pump and method/sequence execution before the system runs dry or an analysis is corrupted.
The bottle filling feature fails if multiple solvent inlets are put into one solvent bottle! ➔ In that case implement a minimum pressure limit (see ) to avoid that the pump runs dry when solvents are empty.

Solvent Information

Observe the following recommendations on the use of solvents.
Follow recommendations for avoiding the growth
Small particles can permanently block capillaries and valves. Therefore,
always filter solvents through 0.4 µm filters.
Avoid or minimize the use of solvents that may corrode parts in the flow
path. Consider specifications for the pH range given for different materials like flow cells, valve materials etc. and recommendations in subsequent sections.
Solvent compatibility for stainless steel in standard LC systems
Stainless steel is inert against many common solvents. It is stable in the presence of acids and bases in the pH range specified for standard HPLC (pH 1 – 12.5 ). It can be corroded by acids below pH 2.3 . In general following solvents may cause corrosion and should be avoided with stainless steel: Solutions of alkali halides, their respective acids (for example, lithium
iodide, potassium chloride, and so on) and aequous solutions of halogenes High concentrations of inorganic acids like nitric acid, sulfuric acid and
organic solvents especially at higher temperatures (replace, if your chromatography method allows, by phosphoric acid or phosphate buffer which are less corrosive against stainless steel).
Halogenated solvents or mixtures which form radicals and/or acids, for
This reaction, in which stainless steel probably acts as a catalyst, occurs quickly with dried chloroform if the drying process removes the stabilizing alcohol.
Chromatographic grade ethers, which can contain peroxides (for example,
THF, dioxane, di-isopropylether) such ethers should be filtered through dry aluminium oxide which adsorbs the peroxides.

Prevent Blocking of Solvent Filters and Algae Growth

Prevent Blocking of Solvent Filters and Algae Growth
Contaminated solvents or algae growth in the solvent bottle will reduce the lifetime of the solvent filter and will influence the performance of the module. This is especially true for aqueous solvents or phosphate buffers (pH 4 to 7). The following suggestions will prolong lifetime of the solvent filter and will maintain the performance of the module.
Use a sterile, if possible amber, solvent bottle to slow down algae growth.
Filter solvents through filters or membranes that remove algae.
Exchange solvents every two days or refilter.
If the application permits add 0.0001 – 0.001 M sodium azide to the solvent.
Place a layer of argon on top of your solvent.
Avoid exposure of the solvent bottle to direct sunlight.
Never use the system without solvent filter installed.

Algae Growth in HPLC Systems
Algae Growth in HPLC Systems
The presence of algae in HPLC systems can cause a variety of problems that may be incorrectly diagnosed as instrument or application problems. Algae grow in aqueous media, preferably in a pH range of 4-8. Their growth is accelerated by buffers, for example phosphate or acetate. Since algae grow through photosynthesis, light will also stimulate their growth. Even in distilled water small-sized algae grow after some time.
Instrumental Problems Associated With Algae
Algae deposit and grow everywhere within the HPLC system causing: Blocked solvent filters or deposits on inlet or outlet valves resulting in
unstable flow, composition or gradient problems or a complete failure of the pump.
Small pore high pressure solvent filters, usually placed before the injector
to plug resulting in high system pressure.
PTFE frits blockage leading to increased system pressure.
Column filters to plug giving high system pressure.
Flow cell windows of detectors to become dirty resulting in higher noise
levels (since the detector is the last module in the flow path, this problem is less common).
How to Prevent and-or Reduce the Algae Problem
Always use freshly prepared solvents, especially use demineralized water
which was filtered through about 0.2 µm filters.
Never leave mobile phase in the instrument for several days without flow.
Always discard old mobile phase.
Use the amber solvent bottle (Solvent bottle, amber (p/n 9301-1450))
supplied with the instrument for your aqueous mobile phase.
If possible add a few mg/l sodium azide or a few percent organic solvent to
the aqueous mobile phase.

When to Use a Vacuum Degasser

When to Use a Vacuum Degasser
The pump does not necessarily require degassing. But for the following conditions the vacuum degasser is recommended: if your detector is used with maximum sensitivity in the low UV wavelength
if your application requires highest injection precision, or
if your application requires highest retention-time reproducibility
(mandatory at flow rates below 0.5 mL/min).
Operational Hints for the Vacuum Degasser
If you are using the vacuum degasser for the first time, if the vacuum degasser was switched off for any length of time (for example, overnight), or if the vacuum degasser lines are empty, you should prime the vacuum degasser before running an analysis.
The vacuum degasser can be primed either by drawing solvent through the degasser with a syringe or by pumping with the pump.
Priming the degasser with a syringe is recommended, when: vacuum degasser is used for the first time, or vacuum tubes are empty, or
changing to solvents that are immiscible with the solvent currently in the
vacuum tubes.
Priming the vacuum degasser by using the pump at high flow rate (3 – 5 mL/min) is recommended, when: pump was turned off for a length of time (for example, during night) and
volatile solvent mixtures are used, or solvents have been changed.
For more information see the Agilent 1260 Infinity Standard Degasser User Manual (p/n G1322-90012).
1260 Binary Pump VL User Manual
When to Use the Active Seal Wash Option
When to Use the Active Seal Wash Option
Concentrated buffer solutions will reduce the lifetime of the seals and pistons in your binary pump. The active seal wash option allows to maintain the seal lifetime by flushing the low pressure side of the seals with a wash solvent.
The seal wash option is strongly recommended if buffer concentrations of 0.1 M or higher are used regularly with the pump.
The active seal wash option kit can be ordered by quoting Active Seal Wash Option kit (p/n G1312-68721).
The seal wash option comprises a peristaltic pump, secondary seals, gaskets, seal holders and tubing for both pump heads. A bottle of premixed water/isopropanol (90 /10 vol%) is placed in the solvent cabinet and connected to the peristaltic pump as described in the technical note that comes with the active seal wash kit.
Always use a mixture of HPLC-grade water (90 %) and isopropanol (10 %) as wash solvent. This mixture prevents bacteria growth in the wash bottle and reduces the surface tension of the water. In order to avoid accumulation of buffer salts or impurities, regularly replace the washing solution using fresh solvents.
The operation of the peristaltic pump can be controlled from the data system or the Instant Pilot.
For adding a seal-wash option, please contact your local Agilent Technologies service representative.

When to Use Alternative Seals

When to Use Alternative Seals
The standard seals for the binary pump can be used for most applications. However, normal phase applications (for example, hexane) are not compatible with the standard seals. They cause extremely high abrasion and significantly shorten seal life time.
For the use with normal phase applications special polyethylene pistons seals (yellow color, PE seals (pack of 2) (p/n 0905-1420)) are available. These seals have less abrasion compared to the standard seals.
The seal wear-in procedure causes problems to the normal phase seals (yellow).
They will be destroyed by the procedure.
➔ DO NOT apply the seal wear-in procedure performed to normal phase seals.
1 Remove the standard seals from the pump
2 Install normal phase seals.
Polyethylene seals have a limited pressure range of 0–200 bar. When used above 200 bar, their lifetime will be significantly reduced.

How to Optimize the Compressibility Compensation Setting

How to Optimize the Compressibility Compensation Setting
The compressibility compensation default settings are 50 × 10-6 /bar (best
for most aqueous solutions) for pump head A and 115 × 10-6 /bar (to suit
organic solvents) for pump head B. The settings represent average values
for aqueous solvents (A side) and organic solvents (B side). Therefore it is
always recommended to use the aqueous solvent on the A side of the pump
and the organic solvent on the B side. Under normal conditions the default
settings reduce the pressure pulsation to values (below 1 % of system
pressure) that will be sufficient for most applications. If the
compressibility values for the solvents used differ from the default settings,
it is recommended to change the compressibility values accordingly.
Compressibility settings can be optimized by using the values for various
solvents described in
If the solvent in use is not listed in
the compressibility table, when using premixed solvents and if the default
settings are not sufficient for your application the following procedure can
be used to optimize the compressibility settings:

1 Start channel A of the binary pump with the required flow rate.
2 Before starting the optimization procedure, the flow must be stable. Use
degassed solvent only. Check the tightness of the system with the pressure test (see 3 Your pump must be connected to a data system or Instant Pilot with which
the pressure and %-ripple can be monitored, or connect an external measurement device to the analog pressure output (see 4 Start the recording device with the plot mode.
5 Starting with a compressibility setting of 10 × 10-6 /bar increase the value
in steps of 10. Re-zero the integrator as required. The compressibility compensation setting that generates the smallest pressure ripple is the optimum value for your solvent composition.

Test Functions and Calibration

This chapter describes the tests for the module.
Test Functions and Calibration
Pressure Test

The pressure test is a quick, built-in test designed to demonstrate the pressure-tightness of the system. The test involves monitoring the pressure profile while the binary pump runs through a predefined pumping sequence. The resulting pressure profile provides information about the pressure tightness of the system.
The test begins with the initialization of both pumpheads. After initialization, pistons A1 and B1 are both at the top of their stroke. Next, pump A begins pumping solvent with a flow rate of 510 µL/min and stroke of 100 µL. The binary pump continues to pump until a system pressure of 390 bar bar is reached.
For this test channel A is active, which is directly connected to chamber 2 in channel B, see o test the pressure tightness of the pump use the leak test, see When the system pressure reaches 390 bar bar, the binary pump switches off. The pressure drop from this point onwards should be no more than 2 bar/min.
1260 Binary Pump VL User Manual
Test Functions and Calibration
Positioning the Blank Nut
To test the complete system's pressure tightness, the blank nut should be positioned at the column compartment outlet (or the outlet of the last module before the detector).
If a specific component is suspected of causing a system leak, place the blank
nut immediately before the suspected component, then run the Pressure Test
again. If the test passes, the defective component is located after the blank nut.
Confirm the diagnosis by placing the blank nut immediately after the
suspected component. The diagnosis is confirmed if the test fails.

Make absolutely sure that all parts of the flow path that are part of the test are flushed very thoroughly with isopropanol before starting to pressurize the system! Any trace of other solvents or the smallest air bubble inside the flow path definitely will cause the test to fail! Running the test from the Agilent Lab Monitor & Diagnostic Software

Test Functions and Calibration
Evaluating the Results
The sum of all leaks between the pump and the blank nut will be indicated by a pressure drop of >2 bar/minute at the plateau. Note that small leaks may cause the test to fail, but solvent may not be seen leaking from a module.
Please notice the difference between an error in the test and a failure of the test! An error
means that during the operation of the test there was an abnormal termination. If a test
failed, this means that the results of the test were not within the specified limits.
If the pressure test fails: Ensure all fittings between the pump and the blank nut are tight. Repeat the
pressure test.
Often, it is only a damaged blank nut itself (poorly shaped from overtightening) that causes a failure of the test. Before investigating any other possible sources of failure make sure that the blank nut you are using is in good condition and properly tightened! If the test fails again, insert the blank nut at the outlet of the previous
module in the stack (eg. autosampler, port 6 of the injection valve), and repeat the pressure test. Exclude each module one by one to determine which module is leaking.
If the pump is determined to be the source of the leak, run the leak test.

The test involves monitoring the pressure profile as the binary pump runs through a predefined pumping sequence. The resulting pressure profile provides information about the pressure tightness and operation of the binary pump comp The test begins with the initialization of both pumps. After initialization, pistons A1 and B1 are both at the top of their stroke. Next, the pump begins pumping solvent with a flow rate of 150 µL/min, stroke of 100 µL, and a composition of 51 % A, 49 % B. Both pumps deliver for one complete pump cycle. At the end of this step, pistons A1 and B1 are at the top of their stroke. The pump continues pumping solvent with a flow rate of 150 µL/min. Channel A delivers for one pump cycle (first, piston A2 delivers, then piston A1), followed by channel B (piston B2, then piston B1), both channels with a stroke of 20 µL. Just before the start of the first plateau, piston A2 delivers with a flow rate of 50 µL/min for approximately 8 s.

If solvent filter is blocked Concentrated nitric acid (35 %) Remove solvent inlet tube from the adapter at the AIV Small particles can permanently block the capillaries and valves of the module.
Damage of the module.
➔ Always filter solvents.
➔ Never use the module without solvent inlet filter.
If the filter is in good condition the solvent will freely drip out of the solvent tube (hydrostatic pressure). If the solvent filter is partly blocked only very little solvent will drip out of the solvent tube.
When opening capillary or tube fittings, solvents may leak out.
The handling of toxic and hazardous solvents and reagents can carry health risks.
➔ Observe appropriate safety procedures (for example, wear goggles, safety gloves and protective clothing) as described in the material handling and safety data sheet supplied by the solvent vendor, especially when toxic or hazardous solvents are used.
Cleaning the Solvent Filter
1 Remove the blocked solvent filter from the bottle-head assembly and place
it in a beaker with concentrated nitric acid (35%) for one hour.
2 Thoroughly flush the filter with LC grade water (remove all nitric acid,
some columns can be damaged by concentrated nitric acid; check with pH indicator).

Seal Wear-in Procedure
Seal Wear-in Procedure
This procedure is required for black PTFE seals (standard applications, p/n 5063-6589), but it will damage the yellow PE seals (normal phase applications, p/n 0905-1420).
➔ Do not run the seal wear-in procedure if PE seals are installed in the pumphead.
1 Put a bottle with 100 ml of isopropanol in the solvent cabinet and place the
solvent intake filter of the pump head you want to wear in into this bottle.
2 Screw the PEEK adapter 1/4-28 to 10-32 (p/n 0100-1847) onto the active
inlet valve and connect the inlet tube from the bottle head directly to it.
3 Connect the Restriction capillary (p/n 5022-2159) to the purge valve.
Connect its other end to a waste container.
4 Open the purge valve and purge the system for 5 min with isopropanol at a
flow rate of 2 mL/min.
5 Close the purge valve, set the flow to a value that gives a pressure of
350 bar. Pump 15 min at this pressure to wear the seals in. The pressure can be monitored on the analog output connector of the pump, with the Instant Pilot, chromatographic data system or any other controlling device connected to your pump.
6 Turn OFF the pump, slowly open the purge valve to release the pressure
from the system, disconnect the restriction capillary and reconnect the outlet capillary to the purge valve. Reconnect the intake tubing to the solvent selection valve and the connecting tube from the solvent selection valve (if installed) to the AIV.
7 Purge your system with the solvent used for your next application.

The CAN bus is a serial bus with high speed data transfer. The two
connectors for the CAN bus are used for internal module data transfer and synchronization.
One analog output provides signals for integrators or data handling
The interface board slot is used for external contacts and BCD bottle
number output or LAN connections.
The REMOTE connector may be used in combination with other analytical
instruments from Agilent Technologies if you want to use features such as start, stop, common shut down, prepare, and so on.
With the appropriate software, the RS-232C connector may be used to
control the module from a computer through a RS-232C connection. This connector is activated and can be configured with the configuration switch.
The power input socket accepts a line voltage of 100 – 240 VAC ± 10 % with a
line frequency of 50 or 60 Hz. Maximum power consumption varies by module. There is no voltage selector on your module because the power supply has wide-ranging capability. There are no externally accessible fuses, because automatic electronic fuses are implemented in the power supply.

12 Hardware Information
Overview Interfaces
The CAN is inter-module communication interface. It is a 2-wire serial bus system supporting high speed data communication and real-time requirement.
The modules have either an interface slot for an LAN card (e.g. Agilent G1369B/C LAN Interface) or they have an on-board LAN interface (e.g. detectors G1315C/D DAD and G1365C/D MWD). This interface allows the control of the module/system via a PC with the appropriate control software.
If an Agilent detector (DAD/MWD/FLD/VWD/RID) is in the system, the LAN should be connected to the DAD/MWD/FLD/VWD/RID (due to higher data load). If no Agilent detector is part of the system, the LAN interface should be installed in the pump or autosampler.
The RS-232C connector is used to control the module from a computer through RS-232C connection, using the appropriate software. This connector can be configured with the configuration switch module at the rear of the module. Refer to Communication Settings for RS-232C.
There is no configuration possible on main boards with on-board LAN. These are pre-configured for 19200 baud,
8 data bit with no parity and
one start bit and one stop bit are always used (not selectable).
The RS-232C is designed as DCE (data communication equipment) with a 9-pin male SUB-D type connector. The pins are defined as: 1260 Binary Pump VL User Manual

12 Hardware Information
APG Remote
The APG Remote connector may be used in combination with other analytical instruments from Agilent Technologies if you want to use features as common shut down, prepare, and so on.
Remote control allows easy connection between single instruments or systems to ensure coordinated analysis with simple coupling requirements.
The subminiature D connector is used. The module provides one remote connector which is inputs/outputs (wired- or technique).
To provide maximum safety within a distributed analysis system, one line is
dedicated to SHUT DOWN the system's critical parts in case any module detects
a serious problem. To detect whether all participating modules are switched
on or properly powered, one line is defined to summarize the POWER ON state
of all connected modules. Control of analysis is maintained by signal readiness
READY for next analysis, followed by START of run and optional STOP of run
triggered on the respective lines. In addition PREPARE and START REQUEST may
be issued. The signal levels are defined as:
standard TTL levels (0 V is logic true, + 5.0 V is false),
fan-out is 10 ,
input load is 2.2 kOhm against + 5.0 V, and
output are open collector type, inputs/outputs (wired- or technique).
All common TTL circuits operate with a 5 V power supply. A TTL signal is defined as "low" or L when between 0 V and 0.8 V and "high" or H when between 2.0 V and 5.0 V (with respect to the ground terminal).
1260 Binary Pump VL User Manual
