Conditioning the Analytical EGC
1. Set a small temporary waste container (for example, a beaker) next to the
EG. Direct the yellow backpressure coil from the EGC
OUTLET
port to
the waste container. The backpressure must be at least 1.4 MPa (200 psi).
2. On the Chromeleon 7 ePanel Set or Chromeleon 6.8 panel tabset, select
the following settings:
a. DC panel: Verify that the suppressor Mode is off.
b. EG panel: Verify that the CR-TC is off.
c. Pump panel:
•
Gradient pump only: Select the correct eluent channel (A, B, C,
or D).
•
All pumps: Set the flow rate to 1.0 mL/min. This turns on the
pump flow, also.

Analytical EGC Conditioning:
EGC concentration at 50 mM
Pump at 1.0 mL/min for 30 min
0.5 mL/min, 7 MPa (1000 psi)

To avoid damaging the suppressor and CR-TC, always turn them off
before conditioning the EGC. The pump flow is on during conditioning;
however, no flow reaches the suppressor or CR-TC.
