GE AKTApure - Pressure Monitors

2.4.12 Pressure monitors
Introduction
This section describes the location and function of the pressure monitors.
Up to four pressure monitors are included in ÄKTA pure.
Function of the system pump and the sample
pump pressure monitors
Up to four pressure monitors are included in ÄKTA pure. One pressure monitor is always connected
to the system pumps and one pressure monitor is part of the Sample pump (S9 or S9H). The monitors
of the pumps are both labelled R9.
The System pump pressure monitor measures the pressure after the system pumps, the system
pressure. The pressure monitor of the sample pump measures the pressure after the sample pump,
the sample pressure. To provide a reading of the highest pressure in the system there are connections
to all pump cylinders.
The pressure monitor also contains pump flow restrictors in order to stop siphoning effects. Siphoning
effects can occur if tubing in the system is disconnected while the inlet tubing is immersed in buffers
that are placed on a higher level than the pump.
