Maintaining the FID 8
Maintaining Your GC 179
8 Hold at temperature for 30 minutes or until the baseline
settles at a lower value. The baseline will typically rise, then
fall to a final value lower than the initial baseline.
9 Restore the analytical method and allow the FID to
equilibrate.
10 Check the FID output value. It should be lower than the first
reading. If it is not, contact your Agilent service
representative.
Without a column installed, a clean system baseline should
be
20 pA.
11 If the column is not installed in the FID, install it. (See “To
Install a Capillary Column in the FID” on page 155.)
