To Check the FID Baseline
1 With the column installed, load your checkout method.
2 Set the oven temperature to 35 °C.
3 Show the detector output signal in Status. Go to Home > Status listing > +Add. Select the
detector’s output from the drop-down list, then touch Add.
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 161.
