“…A promising method of preparing a full range of new adsorbents suitable for gassolid chromatography is to use crystals of organic compounds with high melting points. Some papers have been published in this field but it seems that the potentialities of this method have not yet been fully realized (11)(12)(13)(14)(15)(16)(17).…”

Aromatic amines, pyridine, picolines, and lutidines have been separated by gas-solid chromatography with symmetrical elution peaks, using cobalt phthalocyanine as stationary phase on graphitized carbon black support. The performance of conventional packed columns and of porous-layer open-tube columns using the same adsorbent and sample components are compared. A procedure is described for the preparation of porous-layer open-tube capillary columns having selectivities different from those obtained with graphitized carbon black in the analysis of geometrical isomers of polar compounds.Recently, we reported the preparation and the application of porous-layer open-tube capillary columns, whose walls were covered with a thin layer of graphitized carbon black (1).The procedure used to prepare the adsorptive layer was similar to the one used by Halasz and coworkers (2-4), who coated the walls of capillary columns with a thin layer of an adsorbent such as graphitized carbon black or Fe203 modified with a liquid stationary phase.These open-tube capillary columns coated with a thin layer of graphitized carbon black widen the scope of gas-solid chromatography because they have higher column efficiency and speed of separation and can be operated at lower temperatures than conventional packed columns (5, 6), packed capillaries (7), and even conventional porous-layer open-tube columns (8). The reason for this is that the amount of stationary phase per unit column length is relatively small in the new open-tube column, thus favorable phase ratios can be obtained.Mohnke and Saffert (9) in an early work have prepared a porous layer of silica by etching the inner wall of glass capillary columns to separate hydrogen isotopes. Bruner, Cartoni, and Possanzini (10) have prepared porous-layer open-

“…Manganese oxide was studied as an adsorbent (328), and the adsorption of polar compounds on amorphous boron was investigated with the results indicating chemisorption and reaction (200) . Various solids derived from phthalic acid were comprehensively examined as adsorbents in a study of Heveran (250,251), and a comparison of the selectivity of alkali metal halides for organic isomers and homologs was the subject of a study by Guran and Rogers (219).…”
