Maintaining the FID 11
Maintaining Your GC 225
To Check the FID Baseline
1 With the column installed, load your checkout method.
2 Set the oven temperature to 35 °C.
3 Press [Front Detector] or [Back Detector], then scroll to
Output.
4 When the flame is lit and the GC is ready, verify that the
output is stable and < 20 pA.
If the output is not stable or > 20 pA, the system or gas
may be contaminated. If this contamination is isolated to
the detector, then bakeout the FID. (See “To Bakeout the
FID” on page 229.)
