Plugged Bpr Decontamination; Preparing For Storage Or Shipping - Agilent Technologies InfinityLab LC Series User Manual

Plugged BPR Decontamination

Decontamination of plugged BPR heads may require more aggressive solvents.
In this case use the following procedure:
1 Depressurize the SFC Control Module completely.
2 Disconnect the BPR inlet and outlet tubes from the BPR drawer.
3 Attach the Inlet tube via a transfer line to waste.
4 Attach a solvent pump to the outlet tube of the BPR head
5 Prime the pump with a suitable solvent for the obstructing material.
6 Flush backwards with strong solvent at 1 mL/min for 20 minutes. Do not
exceed a pressure of 400 bar.
7 If the pump cannot transfer fluid at less than 400 bar discontinue the
operation and perform steps to exchange the BPR head.
8 If the backflush is successful, rinse the BPR head with Isopropanol for 10
minutes at 1 mL/min to clear the strong solvent.
9 Reconnect the BPR inlet and outlet lines.
10 Complete the standard decontamination procedure listed above

Preparing for storage or shipping

If the SFC control module needs to be stored in other than its operational
location, it is best to store it in the original factory packaging. This packaging
can also be used to reship the device to a secondary location. If the original
packaging is unavailable, the unit should be stored upright and preferably
covered in a plastic bag or wrap to prevent exposure to dust.
To prepare the unit for storage use the following procedure:
1 Follow the standard decontamination procedure.
2 Depressurize the SFC system completely.
3 Power off the unit.
4 Remove the front panel.
5 Disconnect the wash pump transfer line from the autosampler.
6 Drain the wash pump lines of fluid.
