268 Maintaining Your GC
14 Maintaining the NPD
To Install a Capillary Column in the NPD
1 Gather the following materials:
• Column
• Ferrule(s) (See “Consumables and Parts for the NPD”
on page 260.)
• Column nut
• Column cutter
• 1/4- inch open- end wrench
• Septum
• Isopropanol
• Lab tissue
• Lint- free gloves
2 Load the GC maintenance method and wait for the GC to
become ready.
If using the adaptable detector, verify that the adapter is
installed. (See “To Attach a Capillary Column Adapter on
an Adaptable NPD” on page 266.)
Be careful! The oven, inlet, and/or detector may be hot enough to
cause burns. If the oven, inlet, or detector is hot, wear
heat-resistant 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.
