B.16.1 EluGen Cartridge Backpressure Requirements
The EluGen cartridge requires at least 14 MPa (2000 psi) of backpressure
for optimal removal of electrolysis gas from the eluent produced by the
cartridge. During system equilibration (see
Section B.16 ), monitor the
system pressure and verify that it is between 14 and 20 MPa (2000 and
3000 psi). A system backpressure of 16 MPa (2300 psi) is ideal.
If the pressure is too low, install a backpressure coil between the injection
valve and the eluent outlet. The backpressure coils listed in the table
below are included in the ICS-2000 Ship Kit (P/N 064375).
Connect one end of the backpressure coil to port
P
(
2
) on the injection
valve; connect the other end to the
TO INJ VALVE IN - P/ELUENT OUT
line
or to the mixer outlet, if an EGC CO3 Mixer is installed.
B.17 Verifying Operational Status
After the system has equilibrated, verify the actual pump pressure and stability by
monitoring the pump pressure reading on the Chromeleon Control panel (or the
touch screen
HOME
page). Write down the short-term pressure fluctuations; they
should be less than 0.13 MPa (20 psi).
