摘要：

The evaluation of specific retention volumes in gas chromatography is subject to several sources of error. The use of wall-coated open-tubular columns should yield better values for specific retention volumes. However, on scaling down the flow-rate of the carrier gas, mass of stationary phase and column head pressure, new sources of error are introduced. A careful consideration of the possible sources of error is presented. It was found that, for the use of capillary columns, the classical equation describing the specific retention volume may be modified so that no flow-rates, column head and outlet pressures or mass of stationary phase in the column are necessary in order to obtain correct specific retention volumes.
