Abstract

Abstract Solvent trapping is described as pre-chromatography of sample components on a layer of condensed solvent in the column inlet. As an approximation, the influence of sampling on the chromatography of components is determined by this pre-chromatography. This is the conclusion drawn for an experiment in which different sections of the material eluted from the layer of condensed solvent were analysed. It is therefore not necessary to take the stationary phase into consideration concerning solvent trapping effects.
