Capillary
IC
Capillary IC pumps shipped before February 17, 2011 were rated for lower
operating pressures than the pumps currently being shipped. The older
pumps can be operated at pressures up to 35 MPa (5000 psi) (without
RFIC) and up to 21 MPa (3000 psi) (with RFIC). Before operating at
pressures above these limits, verify that you have the appropriate pump.
•
HPC is stamped on the secondary
pump heads of the older (lower
pressure rated) capillary IC pumps.
•
HPC-2 is stamped on the secondary
pump heads of the newer (higher
pressure rated) capillary IC pumps.
A Capillary Pump High Pressure Upgrade Kit (P/N 075994) is available for
converting a lower pressure rated capillary IC pump to a higher pressure
rated pump.
IMPORTANT
If your system includes a capillary pump linked to an
EGC, check the label on the EG degas (capillary)
cartridge in the IC Cube and verify that 5000 psi is
printed on the label (see the figure on the right).
If 5000 psi is not on the label, you must change the high
pressure limit to 21 MPa (3000 psi) or replace the
cartridge with an EG degas (capillary) cartridge that is
rated for 35 MPa (5000 psi) (P/N 074459).
