The Chemical Micro-Analysis of Binary Gas Mixtures

An apparatus is described for the micro-analysis of mixtures containing (i) carbon monoxide and an inert gas or nitrogen, and (ii) oxygen and an inert gas or nitrogen. The apparatus has been used for analysing samples of the order of 10 mm. at N.T.P. with an accuracy of 1%. The analyser may, however, be modified to permit the analysis of considerably smaller volumes.
