Figure 9-25. Flow Schematic for Conditioning an 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
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.
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.

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.
