Piston backflushing The piston backflushing function automatically flushes the rear piston area
of the pump head upon switch-on and in continuous mode.
Upon switch-on: The rear piston area of the pump head is automatically
flushed for 15 seconds.
In continuous mode: The rear piston area of the pump head is flushed
automatically every 15 minutes, for 15 seconds.
PMax Mode This mode protects the column from excessive fluctuations in pressure. If
the maximum pressure is reached, the user can decide if the pump should be switched off or continue running with constant pressure. You find a detailed description on chromatography software in the corresponding user manual.

More safety-relevant information is listed below:
flammability: Organic solvents are highly flammable. Since capillaries can
detach from their screw fittings and allow solvent to escape, it is prohib­ited to have any open flames near the analytical system.
solvent tray: Risk of electrical shock or short circuit if liquids get into the
device's interior. For this reason, place all bottles in a solvent tray.
solvent lines: Install capillaries and tubing in such a way that liquids can-
not get into the interior in case of a leak.
leaks: Regularly check if any system components are leaking.power cable: Defective power cables are not to be used to connect the
device and the power supply system.
self-ignition point: Only use eluents that have a self-ignition point higher
than 150 °C under normal ambient conditions.
power strip: If several devices are connected to one power strip, always
consider the maximum power consumption of each device.

Computer Control

This section describes how to set up an HPLC system in a local area network (LAN) and how a network administrator can integrate this LAN into your
company network. The description applies to the operating system Win­dows and all conventional routers.
Note: To set up a LAN, we recommend to use a router. That means the fol­lowing steps are required:
2. Hook up the router to the devices and the computer.
3. On the computer, configure the router to set up the network.
4. Install the chromatography software from the data storage device.
5. Switch on the device and run the chromatography software.

Configuring the LAN Settings

The LAN uses only one server (which is normally the router) from that the devices automatically receive their IP address.

Prerequisite In Windows, power saving, hibernation, standby, and screen saver must
be deactived.
In case you use an USB-to-COM box, the option "Allow the computer to
turn off ths device to save power" in the devicemanager must be deacti­vated for all USB hosts.
Only for Windows 7: For the network adapter, the option "Allow the
computer to turn off this device to save power" in the Device Manager must be deactivated.
Process 1. In Windows 7 choose Start
ter.
2. Double-click on LAN Connection.
3. Click on the button Properties.
4. Select Internet Protocol version 4 (TCP/IPv4).
5. Click on the button Properties.
6. Check the settings in the tab General. The correct settings for the DHCP client are: a) Obtain IP address automatically b) Obtain DNS server address automatically
7. Click on the button OK.

Connecting the Cables

A router 3 has several LAN ports 2 and one WAN port 4 that can be used to integrate the LAN into a wide area network (WAN), e.g. a company net-
work or the Internet. In contrast, the LAN ports serve to set up a network from devices operating the HPLC system separately from the company network.

Prerequisite The computer has been switched off.
You will find patch cables for each device and the router in the accessories kit. To connect the router to a WAN, an additional patch cable is required, which is not supplied within the scope of delivery.
There is a patch cable for each device and the computer.
Process 1. Use the patch cable to connect the router and the computer. Repeat this
step to connect all devices.
2. Use the power supply to connect the router to the mains power system.

2. Enter user name and password.
3. Configure the router as DHCP server.
P 6.1L user manual V6890
25 Installation
4. In the router configuration, check the IP address range and make changes if necessary.
Result Once the router has assigned IP addresses to all devices, the chromatogra-
phy software can be used to remotely control the system.

Integrating the LAN into a Company Network

A network administrator can integrate the LAN into your company network. In this case you use the WAN port of the router.
Prerequisite There is a patch cable for the connection.
Process 1. Check that the IP address range of the router and of the company net-
work do not overlap.
2. In case of an overlap, change the IP address range of the router.
3. Use the patch cable to connect the router WAN port to the company net­work.
4. Restart all devices, including the computer.

Controlling Several Systems Separately in a LAN

Devices connected to a LAN communicate through ports, which are part of the IP address. If more than one HPLC system is connected to the same LAN and you plan on controlling them separately, you can use different ports to avoid interference. Therefore, the port number for each device must be changed and this same number must be entered into the device configura­tion of the chromatography software. We recommend to use the same port number for all devices in the same system.
Note: The port is set to 10001 at the factory. You must use the same num­bers in the device configuration of the chromatography software as in the device, otherwise the connection fails.
Process 1. Find out port number and change it on the device.
2. Enter the port number in the chromatography software.
Result The connection is established.

Setting a Static IP Address

Note: Please inform yourself about the IT safety standards valid for your lab-
oratory, before changing the LAN settings. The device is factory set to a dynamic IP address (DHCP). To ensure a per-
manent LAN connection between the chromatography software and the device, we recommend to set a static IP address for certain applications.
Prerequisites The device has been switched on.
Mobile Control has been installed and started.The connection between the Mobile Control and the device has been
established.
Note: You find further information on LAN settings in the chapter Device Settings of the Mobile Control User Manual.

Bleeding the Pump

Before the pump can be used, it must be bleeded.
Mode “Flow on” The pump can only be bled when switched on because the syringe can only
take in liquid in "Flow on" mode. Only then are the valves of a binary pump opened.
Quick suction process For the binary pump, the bleeding process may take a while during initial
start-up because the solvent tubes are filled with liquid for the first time.

matography
Isocratic Mode of sample separation where the composition of a solvent remains
constant
Capillary thin metal or PEEK pipe that connects components and devices within the
chromatography system
Check valve Valve unit built into the pump head which guides the flow of liquid from
the inlet to the outlet.
LAN Local area network (LAN). Network in which HPLC devices and a com-
puter are connected, in order to control the devices.
LED Light-emitting diode
Solvent mobile solvent transporting substances to be separated or isolated
through the column
Ground Protective measure for electroconductive housing parts

a gradient
Mobile Control Mobile application to control and program the whole HPLC system via
wireless LAN.
NPG pump Pump configured to generate a gradient on the low-pressure side. Only
one pump unit is used which contains small doses of the different sol­vents. The solvents are mixed in small mixing cycles by a valve block which is connected upstream. The gradient is generated behind the pump.
Low-pressure side Devices and capillary which are under high pressure in an HPLC system
pH Measure for the acidic or alkaline character of an aqueous solution.
Pump Device which conveys solvents in controlled quantities into a system.
Quaternary pump Pump configured to generate a gradient from four solvents.
Column The column is filled with a matrix which separates the single components
of a substance spatially by interacting with an analyte transported with the solvent to different degrees.
Solvent selection valve Component of the pump that allows selecting from two different solvents
for every solvent channel. With this mechanism the solvent can be changed without having to manually change the system.
Dead volume Volume of capillaries and system components between mixing chamber,
injector and column as well as between column and detector.
