System and method for measuring a quantity of a known gas

Abstract

A system and method for continuously monitoring and measuring a quantity of a reference gas includes providing a reference gas and measuring a thermal conductivity of the reference gas via a gas analyzer and calculating a purity threshold value based on the measured thermal conductivity of the reference gas. A mixture of gases containing the reference gas is then provided and a thermal conductivity of the mixture of gases is continuously measured via the gas analyzer. The measured thermal conductivity of the mixture of gases is compared to the purity threshold value, and a purity threshold level of the reference gas in the mixture of gases is indicated once the measured thermal conductivity of the mixture of gases reaches the purity threshold value.
