1. Prepare sampling port by installing sample probe and
shroud as described in NY DOH method.
2. Turn on Restek Electronic Leak Detector and allow it to
equilibrate for a few seconds prior to use.
3. Insert leak detector probe tip into the open end of the
tubing connected to the sealed sample port.
4. Wait 10 seconds and inject a charge of helium into the
open space of the shroud.
5. Wait several minutes. An alarm will sound if helium is
detected at >10%, indicating a leak in the sample port.

analytical column!
High temperature GC methods are extremely sensitive to carrier
gas impurities such as water and oxygen. Make sure you have clean
carrier gas and frequently check connections and injection
system fittings for leaks using a Restek Electronic Leak Detector.
