Abstract
Capillary columns of 0.3β0.5 mm i.d. packed with 3β to 30βΞΌm silicaβbased stationary phases for liquid chromatography were used for gas chromatographic separation of hydrocarbons. Column efficiencies were evaluated for various commercially available packing material. The best column efficiency was achieved with 5βΞΌm octadecyl group bonded silica gel, the surface of which was coated with a poly (dimethylsiloxane) film. The 30βcm column produced 11,000 theoretical plates.

The HorvathαLin equation was modified to describe the peak dispersion in liquid chromatography for columns packed with nonporous spherical particles. The minimum separation times for compounds with different separation ratios were calculated by employing a series of fundamental equations for nonporo
