To Check the FID Leakage Current
Maintaining Your GC
1
Load the analytical method.
•
Make sure flows are acceptable for ignition.
•
Heat the detector to operating temperature or 300 °C.
2
Turn off the FID flame.
Show the detector output signal in Status. On the GC touch
3
screen go to Home > Status listing > +Add. Select Detector 1
Output (or Detector 2 Output) from the drop-down list, then
touch Add.
4
Verify that the output is stable and < 1.0 pA.
If the output is unstable or > 1.0 pA, turn off the GC and
check for proper assembly of the upper FID parts and
contamination. If this contamination is confined to the
detector, bakeout the FID. (See
page 140.)
