✦ Synopsis

Two graphitized carbon blacks have been evaluated as solid supports (adsorbents) for the chromatographic determination of adsorbate-adsorbent interactions.

Adsorption isotherms were chromatographically derived to provide insight into the behavior of several n-alkanes, aromatic hydrocarbons, and aliphatic alcohols, with four adsorbents functioning as chromatographic packings. These four adsorbents, Carbopack B, Carbopack C, Carbopack B modified with 5% (w/w) Carbowax 20M, and Carbopack C modified with 0.5% (w/w) Carbowax 20M, subsequently were utilized for the chromatographic analyses of the adsorbate groups, in the low coverage (Henry's Law) region.

## Abstract The heats of adsorption of nitrogen, argon, xenon, pentane, cyclohexane and benzene on a typical microporous carbon have been measured by gas‐solid chromatography. An overall comparison of the limiting heats of adsorption on active carbons and on graphitized carbon blacks shows a ratio
