Progress in fiber packed capillary column technology and application

Several kinds of common organic fibers were longitudinally packed into capillary column as the stationary phase taking into account the heat resistance,solvent resistance and the physical strength.Taking advantage of large sample loading capacity and practical retentivity,several successful application were demonstrated specially gas chromatography(GC),liquid chromatography(LC),solid-phase microextration-(SPME) and capillary electrophoresis(CE).The principal technical characteristics of fiber packed capillary column was introduced and the influential factors and operation key points were discussed.it′s the application progress was reviewed,focus on the application of different sorts of fiber packed capillary column in gas chromatography and electrochromatography.The development trends of fiber packed capillary column technology was also presented.
