1. Gather the required supplies and tools.
2. Load the GC maintenance method and wait for the GC to become ready.
3. If using the adaptable detector, verify that the adapter is installed.
4. Place a septum, capillary column nut, and ferrule on the column.
5. Score the column using a glass scribing tool. The score must be square to ensure a
clean break.
6. Break off the column end by supporting it against the column cutter opposite the
scribe. Inspect the end with a magnifying loupe to make certain there are no burrs or
jagged edges.
7. Wipe the column walls with a tissue dampened with isopropanol to remove fingerprints
and dust.
8. Install the capillary column.
If the column ID is greater than 0.1 mm:
a. Gently insert the column into the detector until it bottoms; do not attempt
to force it further.
b. Finger-tighten the column nut, then withdraw the column about 1 mm.
Tighten the nut an additional 1/4 turn with a wrench.
If the column ID is 0.1 mm or less, position the column so it extends above
the ferrule by 48 mm (capillary optimized fitting) or 68 mm (adaptable fitting).
Slide the septum up to hold the column nut and ferrule at this fixed position.
c. Insert the column into the detector. Slide the nut and ferrule up the column
to the detector base. Finger-tighten the column nut until it grips the column.
d. Adjust the column (not the septum) position so that the septum is even with the
bottom of the column nut. Tighten the nut an additional 1/4 turn with a wrench.
• The oven and/or inlet may be hot
enough to cause burns. If either 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.
•
Wear clean, lint-free gloves to prevent
contamination of parts with dirt and
skin oils.
