Abstract
A single gas analyzer is used for analyzing the concentration of two gaseous components such as hydrogen and chlorine in a blend by responding to the chlorine content in the gas blend there being a UV-type reactor for the formation of hydrochloric acid and the operation is such that the gas to be analyzed alternates between a path in which the reaction has taken place and one in which such a reaction has not taken place, for directly measuring the concentration of the gas with a higher concentration and indirectly the concentration of the gas with the lower concentration by determining the depletion the reaction has caused in the higher concentration gas.
