Gow-Mac 21-250 Helium Leak Detector for GC

The Gow-Mac 21-250 gas leak detector can easily and quickly pinpoint gas leaks too small to detect with soap solution without risk of contaminating your GC system. Using liquids to detect gas leaks can be poor economy, especially in a capillary GC system. Even a small amount of liquid leak detector that seeps into a fitting, or through the septum, can damage your column.

The Gow-Mac gas leak detector operates on the same principle as a thermal conductivity detector. The instrument responds to any gas mixture that has a thermal conductivity value different from that of air. With an intrinsically high signal-to-noise ratio, amplification provides maximum usable sensitivity — helium leaks of 1 x 10-5 cc/sec and refrigerant leaks of 11 x 10-4 cc/sec are easily detected. Comes as seen in photos.
