✦ Synopsis

Analytical forrnulae to express the effect of adsorption of carrier gas in gassolid chromatography have been derived from the theory of non-linear ideal chromatography and the Langmuir adsorption theory, They predict improvement of symmetry in peak shape, reduction in retention volume, independence of relative retention on the kind of carrier gas used, and the smaller dependence of retention volume on column temperature when an inert gas is replaced with an adsorptive gas as carrier. The formulae were satisfactorily applied to explain experimental results on the separation of hydrogen isotopes by a series of ammonia-treated molecular sieve 13X columns.
