Abstract
A reactor for removing contaminants such as reactive hydrocarbons from the gas being sampled by gas component determination apparatus is disclosed. A confined path is disposed adjacent a high purity quartz lamp capable of generating low order wavelengths. By selecting the flow rate of the sample gas past the quartz lamp in the presence of ozone, all hydrocarbons can be photo-oxidized or all hydrocarbons with the exception of methane. Apparatus is also disclosed employing the reactor wherein the methane content of a sample gas can be determined. The sample gas is alternately measured as to the quantity of all hydrocarbons contained therein and then measured for methane. The difference between the two readings is indicative of the amount of non-methane hydrocarbons present.
