To Remove the Fused Silica Column from the Transfer Line
1 Gather the following:
• 3/16- inch open end wrench (provided in ship kit)
• 1/4- inch open end wrench
2 Cool down the transfer line and 6 port valve (sample
loop) in the headspace sampler.
3 Cool the GC inlet to a safe handling temperature.
4 If using GC carrier gas control, or if the Headspace
provides the carrier gas flow for the GC, also cool the GC
oven to ambient temperature to prevent column damage.
5 Remove the pneumatics front cover. See “To Remove the
Pneumatics Front Cover”.
CAUTION
Wear clean, lint-free gloves to prevent contamination of parts with
dirt and skin oils.
CAUTION
Disconnecting the transfer line may interrupt GC carrier gas flow.
Cool the GC column oven and inlet as needed to prevent column
damage.
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.
