Effects of micropores on peak shape and retention volume in gas-solid chromatography. Comments

Abstract

completely resolve dimethyl phthalate and dimethyl sebacate, eluted in that order, and could be used for the analysis of compositions containing both these esters, should the need arise.Antarox CO-990 has now replaced polypropylene sebacate because of its lower bleed rate at an operating temperature 40 °C below its maximum of 225 °C, and because of improved separation of triacetin and diacetin. Dimethyl sebacate and dimethyl phthalate, eluted in this order, are not completely resolved by this liquid phase. The results obtained were all within the precision usually expected for gas chromatographic analysis-i.e., ±1% relative.

Measurement of zeolitic diffusivities and equilibrium isotherms by chromatography

“…The latter condition has been considered in greater detail by Habgood and MacDonald ( 1970). For detailed studies of zeolitic diffusion, conventional gravimetric or volumetric methods have the advantage of simplicity and directness.…”
