Maintaining the COC Inlet 7
Maintaining Your GC 107
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 102.)
• 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 114.)
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.
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.
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.
