On-line coupled liquid and gas chromatography system

摘要

Apparatus and method for on-line coupled liquid chromatography and gas chromatography analysis includes a retention gap which allows injection of a substantial volume of sample-carrying eluent and concentrates bands, obviating adverse effects on the resolution or peak shape of the components of interest. The retention gap is used to simultaneously receive and vaporize liquid solvent in a manner highly suitable for purposes of gas chromatographically separating solutes of interest dispersed in the liquid chromatography solvent.
