FID Maintenance Kit Instructions
15
If you have an adaptable FID base – remove the capillary
adapter with a 9/16-inch wrench, and clean any graphite out of
the adapter out with a wire. Optionally, sonicate the part.
Re-install the adapter with a new 1/4-inch Swagelok nut and
graphite/Vespel ferrule or brass front and back ferrule.
Clean or Replace the Jet
Agilent recommends replacing the FID Jet during maintenance.
However, the jet can be cleaned using the following procedure:
1
Run a .010-inch cleaning wire through the tip of the jet.
2
Run the wire back and forth a few times until it moves
smoothly.
Be careful not to scratch the jet.
3
Optional: Immerse the jet in a beaker of aqueous detergent.
Place it in an ultrasonic bath for 1–5 minutes.
4
Rinse the jet in methanol.
5
Air dry the jet.
The FID jet should not be re-used more than once.
CAUTION
Scratches on the FID jet affects its performance. If you choose to
clean the jet, be sure not to scratch or bend the jet.
NOTE
If the jet becomes bent or disfigured during the cleaning process, discard
it and use a new replacement jet.
