24 Operation

Before turning off, if you do not plan to restart the device within shortly.
Use the solvent for flushing that is to be used in the subsequent applica-
tion.
Note: If you used a buffer solution, pay attention to choosing a solvent for
flushing in which the buffer solution is soluble.
The purging process of the pump is limited to a maximum pressure of
5 MPa. If this value is exceeded during the purging process, the pump
switches off automatically. If you are using very small hoses and capillar-
ies, the pressure can be too high.
For how long is
flushing required?
If there are air bubbles in the capillaries, the flow pulsates. As soon as the
flow is constant, the pump is bleeded and flushing can be stopped. The
duration for flushing depends on capillary and hose length as well as the
flow rate.
Control
A device can be operated in different ways:

with chromatography software

with Control Unit

with app Mobile Control
Chromatography Soft-
ware
To control the device with chromatography software, it must be con-
nected to the computer through the LAN interface.
Devices can be controlled with e. g. OpenLAB EZChrom edition version
A.04.05 or higher, ChromGate version 3.3.2 or higher and ClarityChrom
version 3.0.7 or higher.
You will find a detailed description on the chromatography software in the
software manual.
Control Unit To control the device with the external Control Unit,
you have to connect the Control Unit via the firmly
installed cable. The Control Unit is an optional acces-
sory. You will find a detailed description on the Control
Unit in its accompanying user manual.
Mobile Control The Mobile Control is an app for your computer or tablet. To control the
device with the Mobile Control, you need to connect your PC or tablet
with operating system Windows 8 to a WLAN router. The firmware version
of your P 2.1L must be V01.07 or higher. You will find a detailed descrip-
tion on the Mobile Control in its accompanying software manual.
