WebHelium sniffing is a method used for leak testing of larger volumes where the vessel cannot be subjected to high vacuum or it is important to identify exactly where the leak is located. 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.
