To Check FPD Performance (Sample
The tests described in this section provide basic confirmation
that the GC and detector can perform comparably to factory
condition. However, as detectors and the other parts of the GC
age, detector performance can change. The results presented
here represent typical outputs for typical operating conditions
and are not specifications.
The tests assume the following:

Use of an automatic liquid sampler. If not available, use a
suitable manual syringe instead of the syringe listed.

Use of a 10-µL syringe in most cases. However, a 5-µL
syringe is an acceptable substitute for the 1-µL injections
described here.

Use of the septa and other hardware (liners, jets, adapters,
and so forth) described. If you substitute other hardware,
performance can vary.
