Separation Factors in Gas Chromatography

Abstract

IT is generally accepted among those using gas chromatography that for most separations the use of lower temperatures increases the separation factor, though, usually owing to the time taken at low temperatures, there is a limit to the use to which this effect can be put. Capillary columns can, however, be made extremely fast in their operation, and hence low temperatures can be used for separations which normally require temperatures at least 70° C. higher.
