Two methods for the gas chromatographic determination of hydrogen nuclear spin isomers and isotopes were investigated with special reference to their accuracy and practicability. One is based on utilizing two sorts of column packings connected in series; the first contains alumina and the second allumina coated with manganese chloride. The chromatogram may yield four peaks corresponding to p-H/sub 2/, o-H/sub 2/, HD, and D/sub 2/. The other needs two acts for the analysis. A portion of hydrogen sample is introduced on alumina column that gives rise to three peaks corresponding to p-H/sub 2/, o-H/sub 2/ plus HD, and D/sub 2/, respectively. The remaininig portion is introduced on alumina-manganese HD, and D/sub 2/ may be obtained. From these the composition of four hydrogen molecular species may readily be determined. The two methods were applied to the quantitative analysis of hydrogen isomers and isotopes of known composition. All peaks appeared within 5 to 15 min, the composition agreeing with the expected value within plus or minus 2% accuracy. (P.C.H.)
