Summary A new technique of split injection in capillary column Gas Chromatography is evaluated. The sample is introduced in the injector at low temperature and then vaporized by a fast programmed heating. The split is open all the time and the sample amount entering the column is proportional to the preset split ratio. It is demonstrated that no discrimination occurs and that it is possible to inject a very concentrated solution or undiluted sample with a high degree of accuracy and reproducibility in the same injector used for the total sample introduction or solvent — split introduction mode.
