230
Hold at temperature for 30 minutes or until the baseline
8
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.
Check the FID output value. It should be lower than the
10
first reading. If it is not, contact your Agilent service
representative.
Without a column installed, a clean system baseline
<
should be
20 pA.

If the column is not installed in the FID, install it. (See
"To Install a Capillary Column in the FID"
on page 205.)
