1. Locate the yellow 0.5 mL/min, 7 MPa (1000 psi) backpressure coil
(P/N 053765) and a 10-32 to 10-32 coupler (P/N 042627) in the ICS-
2000 Ship Kit (P/N 064375).
2. Use the coupler to connect one end of the backpressure coil to the
TO
INJ VALVE IN - P/ELUENT OUT
line.
3. Connect the other end of the backpressure coil to the coupler on the
mixer inlet.
NOTE The backpressure coil connection is temporary;
it is required only during initial filling of the
mixer.
4. Direct the mixer outlet to a temporary waste container, such as a
beaker.
5. Verify that the suppressor is off.
6. Verify that the Automatically turn on with pump option is not
selected on the ICS-2000 touch screen
SUPPRESSOR
page (see
Section C.9 ). Disabling this option lets you turn on the pump, without
automatically turning on the suppressor.
7. From the ICS-2000 Control panel in Chromeleon or the ICS-2000
touch screen
HOME
page, set the pump flow rate to the rate required
for the application.
8. Turn on the pump.
9. Verify that the system backpressure is between 14 and 16 MPa (2000
and 2300 psi). If necessary, adjust the pressure by adding or removing
backpressure tubing.
10. From the Chromeleon Control panel or the touch screen
ELUENT
GENERATOR
page, set the
EGC-1
concentration to the value required
for your application.
11. Turn on the
EGC-1
current.
To avoid damaging the suppressor always turn off the suppressor
before filling the mixer. The pump flow is on during filling, however,
no flow reaches the suppressor.
