Maintenance
Make sure your column dimensions are correct in relation to
the size of your fused silica. Your column id can not be
greater than 530 um. Refer to your cool on- column inlet
documentation for more information.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
Gather the following:
1
• Lint- free gloves
• Capillary column cutter (5181- 8836)
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.
Cool the GC inlet to a safe handling temperature.
