To Install a Capillary Column with the COC Inlet
1 Gather the following:
• Column nut and ferrule. (See “Consumables and Parts for
the COC Inlet” on page 120.)
• Column cutter
• 1/4-inch and 5/16-inch wrenches
• Lint-free gloves
2 Load the inlet maintenance method and wait for the GC to
become ready.
3 Before installing the column, be sure the correct insert is
installed for the needle and column. (See “To Install an Insert
on the COC Inlet” on page 132.)
4 Place a 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.
WARNING
Be careful! The oven and/or inlet may be hot enough to cause
burns. If either is hot, wear heat-resistant gloves to protect your
hands.
WARNING
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.
CAUTION
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
