A new principle and method have been developed for producing a high-efficiency WCOT column by forming a polyimide capillary tube of l-5 pm wall thickness inside a supporting glass capillary (tube-in-tube system). This polyimide layer is chemically resistant, heat-proof (up to 450Β°C) and mechanically
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
