Setting Up the PL-GPC 220
Running the PL-GPC 220
1
Using the Control software set following parameters as required:
•
Oven temperature
•
Vapor sensor threshold
•
Pump flow rate
Typically, 1 mL/min is used for the RUN flow rate and 0.2 mL/min for
the IDLE and LOW flow rates.
2
Set the oven temperature cut-out on the front panel of the instrument to
5 °C above the set oven temperature.
3
In the oven, remove the barrel connector and install the columns.
4
After installing the columns in the required solvent, manually turn the
pump on.
Ensure there are no leaks from any connections.
5
Stop the flow and close both the inner and the outer oven lids.
6
Put the instrument into RUN mode.
Wait for the oven to stabilize at the Run temperature and Run flow rate to
be established.
7
Purge the DRI reference cell via the Control software for at least 20 min.
Once the DRI baseline has settled after purging the instrument is ready to use.

➔
The oven temperature set point must be at least 10 °C lower than the solvent boiling
point.

If the columns are not already in the solvent that is to be used as eluent they need to be
transferred as indicated by the manufacturer. This can be performed in the PL-GPC 220, but
do not flush the columns through the detectors, simply flush the columns directly to waste.
