Cold trap/reinjection interface for two‐dimensional gas chromatography

A. Hagman, S. O. Jacobsson

Abstract

Abstract The construction and evaluation of an interface for two‐dimensional gas chromatography is described. The interface consists of commercially available components and is attachable to available gas chromatographs without any major modifications. The interface has been constructed so as to permit “heartcutting” as well as solute band concentration. Trapping is performed in a simple cold trap of fused silica. Flow switching is accomplished by Deans switching. Factors of the over‐all chromatographic performance are examined.
