Maintaining Your GC

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.
The split vent trap and line may contain residual amounts of any
samples or other chemicals you have injected into the GC. Follow
your company's safety procedures for handling these types of
substances.
4 Remove the split vent and pressure sensing lines by
loosening the nuts.
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
5 Clean the interface using an ultrasonic bath. Sonicate
twice, then rinse and air dry.
