Limits of Detection
These gases can be detected with the Restek electronic leak detector at the following leak rates:
Minimum Detectable Gas Limits and Indicating LED Color:
Helium, 1.0 x 10-5, red LED
Hydrogen*, 1.0 x 10-5, red LED
Nitrogen, 1.4 x 10-3, yellow LED
Argon, 1.0 x 10-4, yellow LED
Carbon dioxide, 1.0 x 10-4, yellow LED

Gas detection limits measured in atm cc/sec.

Avoid using liquid leak detectors on a GC! Liquids can be drawn into the system and/or into the leak detector.

*Caution: The Restek electronic leak detector should only be used to detect trace amounts of hydrogen in a noncombustible environment. It is NOT designed for determining leaks in a combustible environment. A combustible gas detector should be used for determining combustible gas leaks under any condition. When using it to detect hydrogen, the Restek electronic leak detector may only be used for determining trace amounts in a GC environment.
