Gow Mac 21-050: Leak Detector

Helps you find leaks quickly — 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 Model 21-250 gas leak detector can easily and quickly pinpoint gas leaks too small to detect with soap solution. 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.
