1355242 Electrolytic regeneration of hydrogen CALIFORNIA INSTITUTE OF TECHNOLOGY 12 May 1971 [4 Sept 1970] 14489/71 Heading C7B [Also in Divisions B1 and G3] A system for controlling the flow-rate of carrier gas to a gas chromatography column (see Div. B1-B2 and G2-G3) is also provided with an electrolytic arrangement whereby the carrier gas can be separated from the column effluent for regeneration. The carrier gas, e.g. H 2 , and sample effluent mixture is passed to the inner of two concentric hydrogen permeable electrodes 72, 74 separated by an electrolyte, e.g. a Grp.1 metal hydroxide, which is capable of transporting an oxidized species of the carrier gas. The hydrogen diffusing through electrode 72 is oxidized to water and then regenerated by electrode 74. The hydrogen is then recycled via line 84.
