5.19.3 Hydrating and Conditioning the EPM
Follow the steps below to hydrate the EPM for 5 minutes and then
condition the EPM for 30 minutes.
1. Fill the eluent reservoir with ASTM filtered, Type I (18-megohm)
deionized water.
2. Verify that the suppressor is off.
3. Verify that the EluGen cartridge is off.
4. Verify that the Automatically turn on with pump options are not
selected on the ICS-2000 touch screen
SUPPRESSOR
page (see
Section C.9 ) and
ELUENT GENERATOR
page (see Section C.8 ).
Disabling these options lets you turn on the pump, without
automatically turning on the suppressor and EluGen cartridge.
5. From the ICS-2000 Control panel in Chromeleon or the ICS-2000
touch screen
HOME
page, set the pump flow rate to 1.00 mL/min .
6. Turn on the pump.
7. Run the pump for 5 minutes to hydrate the EPM.
8. Select the following settings from the Chromeleon Control panel or
the touch screen
ELUENT GENERATOR
page:
•
Set the
EGC-1
concentration to 9 mM .
•
Set the
EGC-2
concentration to 1 mM .
9. Turn on the EGC-1 and EGC-2 currents.
10. Run at these settings for 30 minutes.
11. Turn off the EGC-1 and EGC-2 currents.
12. Turn off the pump.
13. Remove the backpressure coil and couplers from the
TO INJ VALVE IN
- P/ELUENT OUT
and
TO SRS/AES REGEN OUT
lines.
14. Reconnect the
TO INJ VALVE IN - P/ELUENT OUT
line to the EGC CO
3
Mixer inlet.
To avoid damaging the suppressor, always turn off the suppressor
before conditioning the EPM and EluGen cartridge. The pump flow is
on during conditioning, however, no flow reaches the suppressor.
