High-Efficiency Fused-Silica Capillary Micro-Packed Columns in Gas Chromatography

Abstract

Abstract Due to convenience in operation, high efficiency, simplicity to prepare and wide range of problems solved, it is expedient to employ capillary micropacked columns suggested several years ago. The sorption capacity of such columns is sufficient for analyzing light compounds and for detecting admixtures. The high mass-exchange velocity facilitates the performance of rapid analysis. The above-suggested columns can be readily adapted to standard gas chromatographs, chromatographs designed for opentubular columns, and chromatograph-mass spectrometers. By analogy with liquid chromatography, it is reasonable to develop high-efficincy gas chromatograph of elevated pressure for broad application of capillary micro-packed columns.
