✦ Synopsis

Micropacked

columns are constructed using graphitized carbon black as a support for gas-liquid-solid chromatography.

Their effectiveness is evaluated in terms of Van Deemter plots, flow-rates, inlet pressure and column capacity. It is shown that such columns, by choosing an appropriate liquid phase, can be used for a wide range of temperatures and types of compound. Analytical applications connected with the analysis of complex organic mixtures in water are discussed. The problems of the analysis of air pollutants are also considered.

In this article, fused silica capillaries with an inner diameter of 250 m were packed with 5-and 10-m spherical and irregular silica particles with pore sizes ranging from 60 to 300 A. The columns were investigated for high-speed Ε½ . separation seconds of light hydrocarbons under gas chromatographic
