| Abstract: | The influence of the conditions of preparation of divinylbenzene-based polymer monoliths on the properties of monolithic capillary columns for use in gas adsorption chromatography was examined. It was found that the polymerization time and the temperature and composition of the polymerization mixture have an effect on the dynamic and chromatographic properties of the columns. The monolithic capillary columns prepared under the optimal synthesis conditions had the height equivalent of a theoretical plate at the level of 20–30 μm, which is an order of magnitude below that of conventional open tubular columns. |
