1. Connect a 10-32 to 10-32 coupler to the mixer inlet and connect the
outlet of the yellow PEEK backpressure coil to the coupler.
2. Direct the mixer outlet to the temporary waste container.
3. Verify that the suppressor is off.
4. 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.
5. Set the pump flow rate to the rate required for the application.
6. Turn on the pump.
7. 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.
8. Set the
EGC-1
concentration to the value required for your
application.
9. Turn on the
EGC-1
current.
10. Run at these settings until a consistent flow of eluent is exiting the
mixer outlet. At a flow rate of 1 mL/min it will take about 16 minutes
to fill a 4-mm mixer and about 5 minutes to fill a 2-mm mixer.
NOTE The void volume of the 4-mm mixer is about
16 mL. The void volume of the 2-mm mixer is
about 5 mL.
11. Turn off the
EGC-1
current.
12. Turn off the pump.
13. Remove the yellow PEEK backpressure coil from the
TO INJ VALVE
IN - P/ELUENT OUT
line and the mixer inlet.
14. Retain the coupler on the mixer inlet.
To avoid damaging the suppressor and CR-TC, always turn off the
suppressor before conditioning the EluGen cartridge. The pump flow
is on during conditioning, however, no flow reaches the suppressor.
