•
Verify that the suppressor and the CR-TC are off.
•
Gradient pump only:
Enter 100% for the reservoir containing the
deionized water.
•
Set the pump flow to 1.0 mL/min. This turns on the pump flow, also.
4. Pump deionized water for 10 minutes.
5. Set the EGC concentration to 50 mM. This turns on the Dionex EGC
power, also.
6. Run at the selected settings (1.0 mL/min at 50 mM) for 30 minutes.
7. Turn off the pump flow. This turns off the power to the Dionex EGC, also.

port.
6. Cut a length of 0.25 mm (0.010 in) ID black PEEK tubing long enough to
connect from the Dionex EGC to the CR-TC
ELUENT IN
port. Connect
one end of this line to the EGC

them off before conditioning the Dionex EGC. The pump flow is on
during conditioning; however, no flow reaches the suppressor and
Dionex CR-TC.
