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.

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.
