WebWhen using a “sniffer” the refrigerant gas must pass through the sensor of the detector in order for it to alarm. This can be difficult at times under certain conditions. Wind can be detrimental to your leak detection efforts, making it hard to … WebTCD works by having two parallel tubes both containing gas and heating coils. The gases are examined by comparing the heat loss rate from the heating coils into the gas. Normally one tube holds a reference gas and the sample to be tested is passed through the other.

WebMay 4, 2024 · Introduce helium into the tank. At this stage, the tank is a slightly higher pressure than the surrounding area within the vacuum chamber, therefore any gas inside the tank will be forced out into the chamber. We can then open the chamber to our mass spectrometer and measure the results.

WebJun 8, 2024 · While a single sniffer test takes two to five minutes, an accumulation test typically requires one to two minutes. Although accumulation tests also use helium as a test gas, they are not as expensive as helium vacuum tests.
