Präparative Gas-Chromatographie

Abstract

Some new developments in Gas Chromatography are mentioned: Capillary Gas Chromatography, adsorption capillaries, detectors, reaction gas chromatography. Preparative Gas Chromatography is discussed in detail. A new theory explaining the velocity profiles in preparative columns is mentioned. Reproducible packing of columns under standardized conditions gives preparative columns of diameters up to 10 cm with plate heights of less than 3 mm. Some approaches to continuous gas chromatography are discussed.
