Abstract
THIS communication describes a simple but effective improvement on the speed and resolution in gas chromatographic analyses by means of a split-temperature column system which has provisions for two or more different temperature regions in the same unit and which provides a means of changing rapidly the temperature in these various regions (patent applied for). Such a system possesses the combined advantages of a single low-temperature system, a single high-temperature system, as well as a temperature-programmed system1, and, usually, can result in an appreciable reduction of the time required for each analysis.
