an allergic reaction from skin contact.
CAUTION—Sparking due to Electrostatic Discharge
Liquid flowing through capillaries can generate static electricity. This
effect is particularly present with insulating capillaries and nonconductive solvents (for example, pure acetonitrile). Discharge of
electrostatic energy might lead to sparking, which could constitute a fire
hazard. Prevent the generation of static electricity near the
chromatography system.
2.3.6 In Case of Emergency
WARNING—Safety Hazard
In case of emergency, disconnect the pump from the power line.
To protect optimal functionality of the Vanquish system, observe these
recommendations on the use of solvents and additives:
• The system must be used with reversed-phase (RP) compatible
solvents and additives only.
• Use only solvents and additives that are compatible with all parts in
the flow path.
For details about the materials that are used in the flow path of the
pump, see the Specifications chapter. For information about the
materials that are used in the flow path of the other modules in the
Vanquish system, refer to the Specifications chapter in the
Operating Manual for the module.
Observe the general guidelines and recommendations on the use of
solvents and additives in the chromatography system (see
section6.5, page 89).
2 • Safety
• Allowed ranges and concentrations (standard system configuration):
♦ pH range: 2-12
♦ Chloride concentration: 1 mol/L or less
• Observe the following:
♦ pH values higher than 9.5 with optical detectors
Avoid using mobile phases with a pH value higher than 9.5
together with optical detectors. This can impair the functionality
and optical performance of the detector flow cell.
♦ pH values of 2 or less or high chloride concentration
With pH values of 2 or less or high chloride concentration, the
application time should be as short as possible. Flush the system
thoroughly after these applications.
♦ Mobile phases containing ammonium hydroxide
In rare cases, a shortened lifetime of reversed-phase (UHMWPE) piston seals has been observed with high pH, ammonium
hydroxide containing mobile phases and prolonged exposure.
NOTICE If the system flow path includes a Vanquish charged aerosol
detector, observe the specific solvent and additive information for
this detector. Refer to the operating manual for the Vanquish charged aerosol detector.
• Follow any specific recommendations presented in other sections of
this manual. Refer also to the operating manuals for all modules in

Thermo Fisher Scientific performs complete testing and evaluation of its
products to ensure full compliance with applicable domestic and
international regulations. When the device is delivered to you, it meets
all pertinent electromagnetic compatibility (EMC) and safety standards
as described in this manual. For details, see section 11.1, page 228.
Changes that you make to the device may void compliance with one or
more of these EMC and safety standards. Changes to the device include
replacing a part or adding components, options, or peripherals not
specifically authorized and qualified for the product by Thermo Fisher
Scientific. To ensure continued compliance with EMC and safety
standards, replacement parts and additional components, options, and
peripherals must be ordered from Thermo Fisher Scientific or one of its
authorized representatives.
2 • Safety
The device has been shipped from the manufacturing site in a safe
condition.
• Two-channel pump with each channel based on a dual-piston in-
parallel design
• Independent drive for each piston for high accuracy and increased
flexibility
• Advanced Thermal Effect Compensation (ATEC) and electronic
compressibility compensation (SmartFlow™) for precise and virtually
pulse-free flow
• Active piston seal wash system for high lifetime of pistons and piston
seals
The piston seal wash system keeps the pistons wet and rinses the
piston seals automatically. This prevents crystallization and particle
deposits on the piston surfaces and seals, which may damage the
components.
• Solvent selector "2 from 6" for increased flexibility
• Purge unit for easy and automatic purging
• Built-in vacuum degasser for enhanced flow stability and best
detector sensitivity
• Easy access to the user-serviceable components and tool-free
maintenance procedures for fast and reliable maintenance
• Easy maintenance because the pump remains in the Vanquish
system stack
For specifications, see section 9.1 Performance Specifications, page 216.
The pump can generate pressures up to 151 MPa with ultra-low
pulsation. The pump is based on a two-channel, dual-piston design with
electronic compressibility compensation.
Each pump head comprises two cylinders that are connected in parallel.
Thus, the solvent passes only one cylinder when the pump is delivering.
To achieve continuous delivery, one cylinder is refilled while the other
cylinder is delivering at the selected flow rate.
The pump uses independent piston drives and highly precise position
and pressure sensors. This leads to high accuracy, increased reliability,
and ultra-low pulsation when delivering compressible liquids. The flow
rate at atmospheric pressure is always kept constant.
Two 3-port solvent selectors allow forming binary gradients from three
solvents per channel. The solvent to be used for each channel is selected
in the user interface.
The vacuum degasser enhances the flow stability and allows best
detector sensitivity by continuously removing air that may be trapped in
the solvents.
The solvent flow is through the pump head, from the inlet assembly to
the pump cylinders, and on to a Y-connector. The Y-connector combines
the solvent flows from the pump head cylinders.
From each Y-connector, the solvent stream is directed to the purge unit,
which combines the two solvent streams, and on to the inline filter.
To keep the pistons wet and rinse the piston seals, the pump has an
active piston seal wash system (seal wash system). Piston seal washing
prolongs the lifetime of the pistons and seals by preventing
crystallization and particle deposits on the piston surfaces and seals,
which may otherwise damage the pistons and seals.
The picture shows the flow path through the seal wash system.
3 • Pump Overview

1 Supply line for seal wash liquid (from autosampler)
The purge unit combines the solvent streams from the pump heads,
connects the system pressure sensor to the flow system, and allows easy
and automatic purging. The pump is shipped from the manufacturing
site with the capillaries and tubing installed to the purge unit.

Leaks are a potential safety issue. The leak sensor inside the pump
monitors the pump for liquid leaks from the flow connections. The liquid
is collected in the leak tray and guided to the drain port. From the drain
port, the liquid is discharged to waste through the drain system of the
Vanquish system.
When the leak sensor detects leakage, the status indicators change to
red and beeping starts to alert you. Follow the instructions in this
manual to find and eliminate the source for the leakage.
If leakage is not resolved after 3 minutes, the pump stops the flow.
The pump is designed to be operated from a computer configured with
the Chromeleon Chromatography Data System (CDS). The Chromeleon
software provides complete instrument control, data acquisition, and
data management.
For a basic description of instrument control and automated sample
analysis with the Chromeleon software, refer to the Vanquish System Operating Manual. Details on control and operation of the pump are
available in the ChromeleonHelp.
TIP The pump can be operated also with other data systems, such as
Xcalibur™. In this case, installation of additional software is required in
addition to the data system software. For details, contact the Thermo
Fisher Scientific sales organization.
A keypad is available inside the pump, allowing you to perform certain
basic functions directly from the pump.
Inspect the shipping container for signs of external damage and, after
unpacking, inspect the pump for any signs of mechanical damage that
might have occurred during shipment.
If you suspect that the pump may have been damaged during shipment,
immediately notify the incoming carrier and Thermo Fisher Scientific
about the damage. Shipping insurance will compensate for the damage

This section describes how to set up the flow connections to and from
the pump and additional flow connections if required.
When setting up flow connections, follow these rules and
recommendations:
Flow connections can be filled with hazardous substances. Observe the
warning messages and precautionary statements presented in
section 2.3 Safety Precautions(see page 22).
5 • Installation
• Dirty components can contaminate the chromatography system.
Contamination leads to poor performance of the modules and entire
system or can even cause damage to the modules and system.
Therefore:
♦ Always wear appropriate gloves.
♦ Place the components only on a clean, lint-free surface.
♦ Keep your tools clean.
♦ Use only lint-free cloth for cleaning.
• For installation instructions and handling guidelines for capillaries,
tubing, and fittings, see section 5.6.3 Connecting Fittings, Capillaries,
and Tubing, page 62.
To set up the additional flow connections and complete the installation,
follow these steps:
TIP Components or connections in the flow path to other system
modules may be closed with plugs to protect the component or
connection during transport. When you remove the plugs to connect the
pump in the system, keep the plugs. You may need them to close the
connections again, for example, for future transport.
1. Connect the pump to the drain system (see section 5.6.4, page 64).
2. Connect the solvent lines (see section 5.6.5, page65).
3. Set up the seal wash system (see section 5.6.6, page 69).
4. Connect the pump to the autosampler (see section 5.6.7, page 77).
NOTICE When you install devices or components to the system, always
flush them to waste before connecting them in the system flow path. To
flush the Vanquish modules, follow the instructions in the Vanquish System Operating Manual.
5.6.2 Guiding Capillaries and Tubing Through the System
Flow connections between the modules of the Vanquish system are
guided through either the tubing chase in the devices or the guide holes
or capillary clips of the devices.
Tubing Chase, Tubing Guide, Tubing Bracket
To guide certain tubes and lines (solvent tubing, wash liquid tubing,
detector waste line) from the top module to the bottom module in the
Vanquish system stack, the stackable modules have a tubing chase on
the inside right.
The tubing chase provides four tubing guides. Each guide can hold up to
three tubes or lines.
In each module, push the tube (or line) into the appropriate guide (see
picture).
Guide holes and capillary clips are provided at specific positions on the
system modules. Route flow connections from one module to the next
module in the Vanquish system through the appropriate guide hole or
capillary clip when instructed to do so in the manual.
1. Insert the Viper capillary into the connection port.
2. Tighten the connection by the knurl.
TIP Note the slot in the knurl. For narrow connections, you can easily
remove the knurls from neighboring capillaries through this slot and
attach them again later.
3. If the connection leaks:
a) Tighten the connection a little more.
b) If leakage continues, remove the capillary.
c) Clean the capillary ends carefully by using a lint-free tissue
wetted with isopropanol.
d) Reinstall the capillary.
e) If the connection continues to leak, install a new Viper capillary.
The following liquids leave the pump through the outlets at the bottom
right of the leak tray:
• Leaking liquid from the leak tray
Leaking liquid collects in the leak tray and flows off through the
drain port outlet into the drain system of the Vanquish system.
• Waste liquid from the purge unit
Waste liquid from the purge unit flows off through the waste outlet
port into the drain system of the Vanquish system. To avoid false
leak alarms, verify that the waste line sits properly in the waste
outlet port. If it does not, liquid from the purge unit may accumulate
in the drain port and activate the leak sensor.

For information about how the liquid is discharged to waste through the
Vanquish drain system, refer to the Vanquish System Operating Manual.
The pump is shipped from the manufacturing site with the solvent lines
installed between the components in the pump. To complete the setup,
install the solvent lines between the pump inlet ports and the solvent
reservoirs.
The flow path determines the pump inlet (component at which the
solvent enters the pump) and the solvent flow through the pump. With
the binary pump, the pump inlets are the solvent selectors. The
operating principle illustrates the solvent flow through the pump (see
section 3.2, page 33).
Parts and tools required
• Solvent reservoir assemblies, including reservoir, reservoir cap, cap
plugs, and retaining guide for the solvent line
5 • Installation
• Solvent lines
• Solvent line filters
• Optional to shut off the solvent flow through the system at the
solvent reservoir
♦ Shut off valve, kit containing one shut off valve and fitting
connections
♦ Tubing cutter
If you want to install shut off valves after initial setup or operation of
the pump, follow the steps in section 6.9.3 Installing Solvent Shut
Off Valves, page 109.
TIP To avoid the formation of gas bubbles in the solvent reservoirs, place
the reservoirs in the system stack on the same level or higher than the
pump. The setup description below assumes that the reservoirs are
placed in the solvent rack.
Preparation
• Assemble the solvent line filter, wearing appropriate clean gloves:
a) Place the frit in the filter holder (bottom part).
b) Make sure that the frit is in a level position.
• On the pump inlet, remove the plug that protects the inlet during
shipment, if applicable.
1. Connect each solvent line to the pump inlet port for which it is
intended (see the labeling on the solvent lines and in the pump).
TIP For easy access to the lower degas chambers, remove the seal wash
detector assembly (funnel and detector). Grasp and pull the assembly
upward by the funnel. The detector including the tubing and cable can
remain connected to the funnel.

2. Route the solvent lines from the pump inlet to the solvent rack,
through the tubing guides in the pump and all modules above the
pump in the system stack. Observe the routing guidelines in the
Guiding Capillaries and Tubing Through the System section in this
manual.
5. Place the solvent reservoirs in the solvent rack. Position the solvent
lines straight in the tubing guides.
6. Slide a filter holder onto each solvent line.
7. Fill the solvent reservoirs with solvent, observing the guidelines and
recommendations in the Use of Solvents and Additives section in this
manual.
Before using a solvent reservoir for the first time, rinse the
reservoirs thoroughly. Use a high-purity solvent for rinsing.
8. Tighten the reservoir caps hand-tight. Press the retaining guide into
the hole in the reservoir cap to ensure that the tubing is kept in
place in the cap.
9. Optional – Required only if you want to install a shut off valve

12. Place the seal wash reservoir in the solvent rack. Position the seal
wash lines straight in the tubing guides.
13. Check the seal wash lines across the entire flow path. Make sure
that the lines are not bent, pinched, or squeezed at any point in the
flow path.
14. Flush the seal wash system (see the next section).
5.6.6.3 Flushing the Seal Wash System
To flush the seal wash system, select one of the following alternatives:
• Turn on the pump.
Whenever the pump is turned on, the pump starts operation with a
seal wash cycle.
• Flush the seal wash system from Chromeleon.
• Flush the seal wash system from hand.
Select this alternative to flush the seal wash system when the pump
is powered off.
To flush the seal wash system from Chromeleon, start a seal wash cycle
by setting the seal wash pump to Active mode (SealWashPump =
Active).
During the seal wash cycle, the seal wash system is automatically filled
with the seal wash liquid. It will take 5 minutes for the liquid to travel
through the entire flow path.
To flush the seal wash system from hand, follow these steps:
1. Disconnect the tubing from the seal wash detector.
No. Description
1 Seal wash detector

2. Insert a syringe into the open end of the tubing.
3. To allow the liquid to travel easily through the seal wash system,
press down the lever of the seal wash pump and hold it in that
position with one hand.
4. Pull out the syringe plunger to draw seal wash liquid into the tubing.
5. Release the lever of the seal wash pump when the liquid reaches the
syringe.
6. Remove the syringe and reconnect the tubing to the connection port
on the seal wash detector.
Mind the port labeling. To ensure correct functioning of the seal
wash detector, the tubing needs to be connected to the port labeled
in.
TIP Before turning on the power to a Vanquish system module for the
first time, verify that the chromatography software is installed on the
data system computer. When the power is turned on, the required USB
drivers are automatically found and the Windows™ operating system
can detect the device.
To turn on the power to the pump, follow these steps:
1. Check that the power button on the front left of the Vanquish
system base (system power button) is pressed in. If the power
button stands out, press the power button to turn on the power on
the system base.
2. Turn on the pump with its main power switch.
Turn the pump off with the main power switch, when instructed to do
so, for example, during maintenance. Pressing the system power button
will not be sufficient to turn off the power to the device completely.
Whenever the power to the pump is turned on, the following sequence
of events occurs:
• The pump performs a self-test.
If the self-test is not successful, the status indicators are red and the
pump is not ready for analysis. Check the Chromeleon Audit Trail for
the related message and take appropriate remedial action.
• The pump starts operation with a seal wash cycle. Before turning on
the pump, check the liquid level in the seal wash reservoir. Consider
checking also the liquid level in the waste container.
For power on/off control during pump operation, see section 6.4,
The information in this chapter assumes that the initial setup of the
pump has already been completed. If this is not the case, refer to the
instructions in chapter5 Installationbefore proceeding (see page 47).
For a basic description of instrument control and automated sample
analysis with the Chromeleon software, refer to the Vanquish System Operating Manual. Details on control and operation of the pump are
available in the ChromeleonHelp.
When operating the pump, pay attention to the following safety
guidelines:
Observe all warning messages and precautionary statements presented
in section 2.3 Safety Precautions(see page 22).
CAUTION—High Luminosity of LED
The high luminosity produced by the LED illuminating the inside of the
pump can be harmful to the eyes. Do not look directly into the light
produced by the LED. Do not use light-focusing instruments for viewing
the light beam.
6 • Operation
NOTICE Pay attention also to the following guidelines:
• When operating the chromatography system, always set the lower
pressure limit for the pump. This prevents damage resulting from
leakage or from running the pump dry.
• If there is evidence of leakage in the pump, turn off the pump flow
and remedy the situation immediately.
• If the pump flow is interrupted, act appropriately to protect the
components in the detector. For details, refer to the Operating
Manual for the detector.
• Always verify that the autosampler is turned on before the pump
flow is on and pressure builds up. If the autosampler is turned off,
for example, after a power failure, stop the pump flow and wait until
the pressure is down to zero before turning on the autosampler or
other modules again.
The pump is designed to be operated mainly from a computer running
with the chromatography software.
In addition, the following elements are available on the pump:
• Keypad
The keypad buttons allow you to perform certain functions directly
from the pump.
• Status indicators
The LEDs (Light Emitting Diodes) on the status indicator LED bar on
the front side of the pump and the STATUS LED on the keypad
provide a quick visual check of the operational status of the pump.
6.3.1 Keypad
STATUS
The keypad inside the pump allows you to perform certain functions
directly from the pump. When you press a button, a short beep confirms
that the function is performed. When the pump is connected in the
Chromeleon software, some functions may not be available from the
keypad (see further down in this section).
Figure 27: Keypad
The STATUS LED provides a quick visual check of the operational status
of the pump. When the doors are closed, the LED bar on the front side
indicates the operational status.
For status details, see section 6.3.2 Status Indicators, page 86.
If beeping alerts you that the pump firmware detected a problem, for
example leakage, beeping continues until you turn off the beep. Pressing
this button turns off the beep for the current alarm. As a standard,
beeping starts again after 10 minutes if the problem is still present or if
the firmware detected another problem.
Pressing the button selects a pump head. The LEDs next to the button
indicate which pump head is selected, with L referring to the left pump
head and R referring to the right pump head. The LED is green when the
pump head is selected. Before performing a Dock or Purge function
from the keypad, select the pump head for which you want to perform
the action.
DOCK
PURGE
Pressing the button moves the pistons of the selected pump head to the
appropriate position for maintenance procedures, such as pump head or
piston replacement, and undocks the pistons.
When undocking is complete, the LED next to the FLOW button starts
flashing green for the selected pump head. The LED continues flashing
while no pistons are docked. Pressing the button again docks the
pistons.
To avoid damage to the pump, remove or install the pump heads only
while the pistons are undocked (LED is flashing).
Pressing the button starts a purge cycle. Pressing the button while a
purge cycle is running stops the cycle.
For more information about purging, see section 6.8, Purging the Pump,
page 98.
FLOW
Pressing the button starts or stops the flow, considering the selected
flow rate, solvent composition, and flow acceleration/deceleration.
When the pump is connected in the Chromeleon software
The LEDs next to the button indicate the following:
LED Description

Green The pump head is delivering.
Green, flashing The pistons are undocked.
The button functionality is as follows when the pump is connected in the
Chromeleon software:
• No injection (sample) or sequence is running:
All functions are available from the keypad.
• An injection (sample) or sequence is running:
The Mute Alarm function remains available from the keypad,
allowing you to turn off the beep for the current alarm.
6.3.2 Status Indicators
The status LED bar on the front side of the pump and the STATUS LED on
the inside keypad provide information about the pump status.
LED Bar
The LED bar provides the information when the pump is closed. When
the pump is connected in the Chromeleon software, the LED bar may
provide less information.
In addition, the Select function remains available from the keypad,
allowing you to select a pump head.

The power switch on the pump is the main switch for power on/off
control. The main power switch is turned on during initial installation of
the pump.
For easier handling, you can use the power button on the front left of
the Vanquish system base (system power button) for power on/off.
Observe the following:
• All modules in the Vanquish system that are connected to the
system base via system interlink cables are turned on or off
simultaneously when the system power button is pressed.
• When the power is on, the system power button is pressed in. When
the power is off, the system power button stands out.
• If the main power switch on a device is off, you cannot turn on the
device with the system power button.
• To turn off a device completely, you have to turn it off with the main
power switch on the device. Pressing the system power button will
not be sufficient to turn off the power to the device completely.
Whenever the power to the pump is turned on, the following sequence
of events occurs:
• The pump performs a self-test.
If the self-test is not successful, the status indicators are red and the
pump is not ready for analysis. Check the Chromeleon Audit Trail for
the related message and take appropriate remedial action.
• The pump starts operation with a seal wash cycle. Before turning on
the pump, check the liquid level in the seal wash reservoir. Consider
checking also the liquid level in the waste container.
Particles entering the chromatography system can block capillaries and
valves, increase wear, and damage the column or system. Especially with
aqueous solvents, algae and other microorganisms can grow and deposit
in the chromatography system and block the solvent line filters. Blocked
capillaries or filters can cause increased or unstable system pressure.
For optimum performance of the chromatography system, observe the
following guidelines:
• Be sure that the substances you are using are compatible with all
parts in the flow path.
• Use high-quality high-purity solvents (filtered) and additives as
required by the application, for example, UHPLC-grade or LC/MSgrade. If a fluorescence detector is used in the system, consider
using fluorescence-grade solvents.
Filtered high-purity solvents are usually labeled accordingly by the
vendor.
6 • Operation
• When preparing salt solutions or buffers and preparation is
complete, use membrane filtration (0.2 µm) to remove any
particulate matter and to reduce microbial growth.
• When using water, use high-quality water for example, UHPLC-grade
or LC/MS-grade (0.2 µm filtered). When you use water from water
purification systems, keep in mind that polymeric contamination
may occur if the purification system is not maintained properly.
• Before filling a solvent reservoir, always rinse the reservoir
thoroughly with a high-purity solvent.
• Use fresh solvents at regular intervals. Avoid adding up (refreshing)
solvents. With premixed solvents, be especially sure that they are
properly prepared and fresh.
• Before changing from a buffer or salt solution to organic solution,
flush the pump thoroughly with de-ionized water.
• When changing to a different type of solvent, make sure that the
new solvent is miscible with the previous solvent. If the solvents are
not miscible, flocculation may occur.
Mix immiscible solvents with an intermediate solvent to replace
them step by step. For example, use isopropanol.
This section gives information on any additional steps that are required
to prepare the pump for operation and sample analysis.
Before Operating the Pump for the First Time
Prepare the pump for the first-time operation, observing the following:
NOTICE Flush the system flow path thoroughly before operating the
pump for the first time:
• When you install devices or components to the system, always flush
them to waste before connecting them in the system flow path. To
flush the Vanquish modules, follow the instructions in the Vanquish
System Operating Manual.
6 • Operation
• Some components of the pump are filled with isopropanol when the
pump is shipped from the manufacturing site. When operating the
pump for the first time, use solvents that are miscible with
isopropanol. If they are not, use an appropriate intermediate
solvent.
• To remove the isopropanol from the pump components:
♦ Verify that the flow cell and the column are not connected in the
flow path.
♦ Purge the pump and then have the pump deliver flow for a short
time.
• Verify that any air bubbles are completely flushed out of the system
flow path.
Before Starting Sample Analysis
Before starting an analysis:
• Check the liquid level in the solvent reservoirs. Verify that the
• Verify that the doors of the modules in the Vanquish system are
closed.
• Make sure that the chromatography system is properly equilibrated.
System equilibration should include the following operations:
♦ Purging the pump (all channels, including those not used for the
application)
♦ Flushing the entire chromatography system with the starting
solvent to rinse out any solvent from a previous analysis run
♦ Warming up (or cooling down) all temperature-controlled
devices in the system to the starting temperature
Temperature-controlled devices can be, for example,
♦ Column compartment and post-column cooler
♦ Sample compartment thermostatting in the autosampler
♦ Flow cell in a fluorescence detector
♦ Evaporation tube in a charged aerosol detector
♦ Turning on the lamp (or lamps) in the UV/VIS detector
♦ Monitoring the pump pressure and pressure ripple and checking
that the pressure is stable and the ripple within reasonable
limits for the application
♦ Monitoring the detector signal and checking whether the
detector signal is stable so that the drift and signal noise are
within reasonable limits for the application
♦ Performing an autozero of the detector baseline
TIP The Chromeleon software supports procedures for automatically
starting a chromatography system in the software (Smart Startup). The
startup procedure includes the operations for system equilibration. For
details, refer to the Chromeleon Help.
The parameters described in this section should be considered for
routine operation of the pump. You can usually access them from the
Chromeleon user interface. If a parameter listed below is not available in
Chromeleon, consider updating the firmware and Chromeleon version.
For more information, refer to Chromeleon Help and documents.
Parameter Description
Compression The compression values of the pump head can provide
valuable information for troubleshooting. For details,
see section 8.5.2, page 211.
Curve You can specify linear or non-linear (curved) gradient
profiles.
• Curve 5 (default setting) is linear. Changes in the
composition of the delivered solvent over time are
constant.
• Curves 1 through 4 are convex upward. Convex
curves cause rapid changes in solvent composition at
the beginning of the gradient and slower changes at
the end. Slope changes over time become extreme
as curves go from 4 (least convex) to 1 (most
convex).
• Curves 6 through 9 are concave upward. Concave
curves cause slower changes in solvent composition
at the beginning of the gradient and rapid changes at
the end. Slope changes over time become extreme
as curves go from 6 (least concave) to 9 (most
concave).
In addition, you can define step gradients directly in
the gradient table (for example, step A and step B).
Thus, more than 11 different options are available to
change the gradient.
6 • Operation
Degasser The degasser is enabled as a standard when the pump
is shipped (Degasser = On). This setting is the
preferred setting.
Flow The allowed flow range is indicated in the dialog box
for the pump in the Chromeleon 7 Instrument
Configuration Manager (Chromeleon 6.8 Server
Configuration). You can change the upper and lower
limit for the flow rate within the allowed range.
Flow ramps Set the flow acceleration and flow deceleration.
Recommendation:
Set the parameters to a value between 1/3 and factor
3 of the (column) flow rate.
Flow acceleration The flow acceleration (Maximum Flow Ramp Up)
determines how fast the pump starts delivering with
the selected flow rate. If the value is too low, it will
take correspondingly long for the pump to build up the
necessary pressure and start delivery the required
flow. If the value is too high, this may impair the
column lifetime.
Flow deceleration The flow deceleration (Maximum Flow Ramp Down)
determines how fast the pump reduces the flow. If the
value is too low, it will take correspondingly long for
the pump to reduce the flow and thus the pressure. If
the value is too high, this may impair the column
lifetime.
Leak detection Leak detection is enabled as a standard when the
pump is shipped (Leak Sensor Mode = Enabled). This
is the preferred setting.
Piston calibration value The Piston Calibration Value property must match the
3-digit calibration value that is imprinted on the rear
of the piston. You have to update the value in the
Chromeleon software, for example, when you install
new pistons (see page 144).
Piston seal washing/rear
seal washing
The seal wash system is enabled and cannot be
disabled. As a standard, the pump performs a seal
wash in the following situations:
• Once per hour
• Each time the pump is turned on
If required, you can start an additional seal wash cycle
or stop a running cycle:
• If the seal wash pump is in Idle mode, select Active
to start a wash cycle.
• If the seal wash pump is in Active mode, select Idle
to stop a running wash cycle.
You can disable the drop counter functionality by
setting Rear Seal Wash Monitoring to Off. Note that
disabling drop detection will not disable the seal wash
system. However, messages relating to the seal wash
system (for example, when the system has run out of
wash liquid) or piston seal leakage will no longer alert
you in the user interface.
Pressure limits The allowed pressure range is indicated in the dialog
box for the pump in the Chromeleon 7 Instrument
Configuration Manager (Chromeleon 6.8 Server
Configuration). You can adapt the upper and lower
pressure limits within the allowed range.
• The lower pressure limit helps to prevent the pump
(and column) from running dry. A typical setting is
1 MPa.
• The upper pressure limit helps to protect the column
from too high pressure. The column and the
application determine the appropriate setting.
When the pump pressure is outside the specified
limits, the Chromeleon software stops the pump flow
and aborts a running queue (or batch).
Pump pressure In the dialog box for the pump in the Chromeleon 7
Instrument Configuration Manager (Chromeleon 6.8
Server Configuration), the Pump_Pressure check box
is selected as a standard when the pump is set up in
Chromeleon. The Chromeleon software uses this
setting to generate the channel for recording the
pump pressure (which corresponds to the column
pressure).
Always record the pump pressure. If a problem occurs,
the information from the pump pressure channel can
provide helpful information to identify and eliminate
the source for the problem.
Purge Purge the pump in the following situations:
• To remove air bubbles that might be trapped in the
system
• When changing to a different type of solvent
For details, see section 6.8 Purging the Pump, page 98.
Solvent composition In the dialog box for the pump in the Chromeleon 7
Instrument Configuration Manager (Chromeleon 6.8
Server Configuration), set the number of the solvents
to be used with the pump. You can change the
standard solvent names (%A1, %A2, %A3, %B1, %B2, %B3) as required. The solvent names appear in the
Chromeleon user interface.
In the Chromeleon Client, set the solvent composition.
For each of the two channels, select the solvent and
percentage of solvent that you want to deliver.
• For channel A, select the solvent by setting
%A_Selector to %A1 or %A2 or %A3. For channel B,
set %B_Selector to %B1 or %B2 or %B3.
• Determine the percentage of solvent that you want
to deliver by setting the percentage for solvent B
(%B). Solvent A automatically delivers the remaining
volume.
Examples:
• To deliver 100% of solvent B2, select %B2 and set %B
to 100%.
• To deliver 100% of solvent A3, select %A3 and set %B
to 0%.
• To deliver 30% of solvent A1 and 70% of solvent B3,
select %A1 and %B3 and set %B to 70%.
Solvent consumption You can monitor the solvent consumption when you
have entered the following information for the related
solvent:
• Volume of solvent in the reservoir (at the beginning
of a sequence)
• Lower limit for the solvent in the reservoir, which is
the minimum volume of liquid that must be available
in the reservoir
The Remain Time property for the solvent reports
the time left until the liquid level is expected to reach
the lower limit. The Chromeleon software calculates
the time from the current flow rate and volume
entered.
• Warning limit when you want to be informed about
the liquid level in the reservoir
When the liquid in the reservoir reaches the lower
limit, the Chromeleon software stops the pump as
specified in the Emergency Method (or Program) if
available or aborts the queue (or batch) and stops the
pump flow.
Waste level You can monitor the liquid level in the waste container
when you have entered the following information:
• Volume of liquid in the waste container at the
beginning of a sequence
• Upper limit for the liquid level in the waste container
The Remain Time property for the waste reports the
time left until the liquid level is expected to reach the
upper limit. The Chromeleon software calculates the
time from the current flow rate and calculated
current liquid level.
• Warning limit when you want to be informed about
Purging the pump means rinsing the pump for a short time at a higher
flow rate, using the selected solvents. From the purge unit, the solvent is
automatically dispensed to waste.
When
• The pump is operated for the first time
To flush out the isopropanol that is present in some components of
the pump when the pump is shipped from the manufacturing site
• One or more solvent lines have been empty
• To remove air bubbles that might be trapped in the system (pump
head, solvent lines) because air bubbles in the system may lead to
the following problems:
Items required
Settings
♦ Pressure pulsation
♦ High noise level or pulsation during pump operation
♦ Non-reproducible analysis
• When changing to a different type of solvent, for example, when
changing to a different analytical method
Solvents suitable for purging
To flush out the isopropanol when operating the pump for the first time,
use solvents that are miscible with isopropanol. If they are not, use an
appropriate intermediate solvent.
The following settings are considered for the purge cycle:
Setting Description
Purge flow The standard setting is 5 mL/min.
You can adapt the setting in Chromeleon if required. The setting
is considered also when purging the pump from the keypad.
Purge time The standard purge time is 5 minutes.
You can adapt the setting in Chromeleon if required. The setting
is considered also when purging the pump from the keypad.
To purge the pump from Chromeleon, follow these steps:
1. For each channel, select the solvent that you want to use for
purging. The solvent names below refer to the standard solvent
names.
For channel A, select the solvent by setting %A_Selector to %A1 or
%A2 or %A3. For channel B, set %B_Selector to %B1 or %B2 or %B3.
2. Determine the percentage of solvent that you want to deliver by
setting the percentage for solvent B (%B). Solvent A automatically
delivers the remaining volume.
Select the channel that you want to purge and the solvent to be
used. For details, see further down in this section.
Recommended: The channel to be purged should deliver 100% of
the volume.
Examples:
♦ To purge channel B with solvent B1 delivering 100%, select %B1
and set %B to 100%.
♦ To purge channel A with solvent A3 delivering 100%, select %A3
and set %B to 0%.
3. Optional
Adapt the settings for the purge flow or purge time if required.
4. Start the purge cycle.
The purge cycle ends automatically when the specified purge time
ends. If you want to stop purging before the purge time ends, turn
off the purge from Chromeleon.
5. Perform a purge cycle for all channels that you want to purge.
To purge the pump from the keypad, follow these steps:
1. Select the channels that you want to purge.
On the keypad, check the LEDs next to the Select button. A green
LED (L or R or both) indicates that the pump head (channel) is
selected. Note the following:
♦ The purge cycle will be performed for the selected pump head
with the most recently used solvent.
♦ When both pump heads are selected, each channel is purged
with the most recently used solvent delivering 50 % of the
volume.
♦ When the pump is operated for the first time, the purge cycle
will be performed for solvent 1 of the selected pump head (A1
or B1, respectively).
Recommended: The channel to be purged should deliver 100% of
the volume. Check and adapt the setting in Chromeleon if
considered necessary.
2. Optional (in Chromeleon)
Adapt the settings for the purge flow or purge time if required.
3. To start the purge cycle, press the Purge button.
Note the following:
♦ The purge cycle ends automatically when the specified purge
time ends.
♦ Pressing the button while a purge cycle is running stops the
