Programmed temperature vaporiser-based injection in capillary gas chromatography

The application of programmed temperature vaporisation (PTV) in capillary I :as chromatographic analysis is reviewed. The development of the different strategies as well as the state of the art are described. As the analytes a re normally enriched in the PTV insert, the quoted papers are subdivided de pending on whether the enrichment was carried out from organic solvents, fr om water or from gaseous media. Furthermore, the possibilities of PTVs for on-line coupling with sample preparation methods or other separation techni ques and their use as thermoreactors are mentioned.
