Gas Sampling
Prepare to take gas sample
Apply 30mL syringe to chamber tube (both valves closed)
At time= 1:00, open both valves
Pull to 15mL, pump back to 0mL, and pull to 30mL
Close both valves
Remove 30mL syringe from chamber tube
Apply sample needle (not SF6 needle) and open syringe valve
Quickly inject sample into first vial, close valve
(Note: If there is significant pressure in the vial; this indicates an un-evacuated vial. The sample should
be quickly-retaken from the chamber and injected in to new evacuated vial.) Note this on the datasheet.
