Pressure Transducer
Flow exiting the secondary pump head is directed to the pressure
transducer (see
), which measures the system pressure.
Pressure readings indicate that the pumping system is delivering smooth,
accurate flow. Pressure readings can be monitored from the Chromeleon
Control panel or the touch screen
HOME
page.
The system pressure should remain consistent (no more than a 3%
difference from one pressure reading to the next). High and low pressure
limits can be used to stop the pump flow if a limit is exceeded. The
pressure limits can be set from Chromeleon (in the Server Configuration
or in the control program) or from the touch screen
PUMP
page (see
for troubleshooting information if a
pressure limit is exceeded.
Pulse Damper
Flow output from the pressure transducer continues to the pulse damper,
which smooths minor pressure variations. From there, flow is directed to
the injection valve and then to the remainder of the chromatography
system.
Piston Seal Wash
The pump includes a piston seal wash assembly that can be set up to
continuously rinse the back of the piston seals to remove salt crystals and
prolong the life of the seals. To use this feature, an external water source
must be connected. For connection instructions, refer to the ICS-2100
installation instructions.
For continued protection of the pump, replace the piston rinse seals (see
) and O-rings in the seal wash assembly every 6 months, or
whenever you replace the main piston seals for the ICS-2100 pump.
