A method and apparatus for determining the composition and the concentration of biocidal gas and other gases contained in a reaction chamber during processing of material contained in the chamber and exposed to the treating gas. A valved pre-evacuated gas-sampling vessel is positioned in the reaction chamber and, thereafter, opened by remote control to receive a gas sample representative of the gaseous atmosphere present in the chamber. The sampling vessel is then closed, removed from the treatment chamber, and connected to apparatus for analyzing the gas in the vessel. The qualitative and quantitative composition of the treating gas is thus determined.
