11 Maintaining the FID
To Replace an FID Jet
1 Gather the following:
• Replacement jet (See “Selecting an FID Jet” on
page 201.)
• T- 20 Torx screwdriver
• 1/4- inch nut driver
• Tweezers
• Compressed, filtered, dry air or nitrogen
• Solvent that will clean the type of deposits in your
detector
• Clean cloth
• Cotton swab
• Lint- free gloves
2 Load the GC maintenance method and wait for the GC to
become ready.
3 If installed, remove the capillary column from the
detector.
4 Remove the FID collector assembly and place it on a
clean cloth. (See “To Replace the FID Collector Assembly”
on page 209.)
Be careful! The oven and/or detector may be hot enough to cause
burns. If the detector is hot, wear gloves to protect your hands.
Wear safety glasses to protect your eyes from flying particles
while handling, cutting, or installing glass or fused silica capillary
columns. Use care in handling these columns to prevent puncture
wounds.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
