Korolev, V. Shiryaeva, T. Popova, A. Kurganov] Monolithic capillary columns based on silica gel were tested in the course of high-speed gas-chromatographic separations of a five-component mixture of C1-C4 hydrocarbons. It was found that short-length monolithic columns could be used because of their high specific efficiency; this allowed us to shorten the column dead time and the duration of analysis. The column performance of about 1000 theoretical plates per second was reached. The test sorbate mixture was completely separated on a 58.5-cm column with an efficiency of about 18 700 theoretical plates in a time shorter than 17 s. It was noted that CO2 and N2O should be predominantly used as carrier gases. Pleiades Publishing, Ltd., 2007 Korolev A.
