•
Verify the cell calibration by pumping deionized water through the
cell (bypassing the column(s) and suppressor). The total background
should be less than 1.0
μ
S.
•
Perform the suppressor off-line regeneration procedure.
a. Disconnect the liquid lines from the suppressor and remove the
suppressor from the ICS-900.
b. Use a syringe to push the following types and amounts of fluid
into the suppressor ports:
•
AMMS® 300: Push about 3 mL of 100 mM H
2
SO
4
through the
ELUENT OUT
port and about 5 mL of 100 mM H
2
SO
4
through the
REGEN IN
port.
•
CMMS® 300: Push about 3 mL of 200 mM NaOH through the
ELUENT OUT
port and about 5 mL of 200 mM NaOH through the
REGEN IN
port.
c. Allow the suppressor to sit for at least 20 minutes to fully hydrate
it.
•
If the problem persists, replace the suppressor (see Section 5.12 ).
This error occurs if you try to calibrate the flow rate when the pump is off, or
it is on, but the flow rate is not 1 mL/min.
To troubleshoot:
•
Before calibrating the flow rate, be sure to press the Start Calibration
button on the Wellness panel. This will automatically start the pump and
set the flow rate to 1 mL/min. For flow rate calibration instructions, see
Section 5.1.5 .
If the injection valve fails to switch positions within 1 second of being
toggled, the ICS-900 Moduleware reports an error to Chromeleon or
Chromeleon Xpress and this error message is displayed.
Flow rate calibration error.
Load/inject valve error.
