## Abstract Capillary columns of 0.3‐0.5 mm i.d. packed with 3‐ to 30‐μm silica‐based 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 eff
A model is proposed for cocurrent gas liquid flow through a packed bed. For a given packing, gas and liquid flow rates, we proposed that (i) liquid holdup is a function only of pressure gradient and liquid flow rate and (ii) pressure gradient is only a function of liquid holdup and gas flow rate. Eq
Sandwiched capillary columns consisting of one or more carbon threads inserted in a glass capillary and coated with a stationary phase have been prepared and the dependence of the performance characteristics on the capillary diameter and on the number of carbon threads has been investigated. Van Dee
