摘要

Apparatus and method for on-line coupled liquid chromatography and gas chromatography analysis. The system includes a high-volume, liquid vaporizing chamber, or interface capillary tube which allows injection of a substantial volume of sample-carrying eluent and concentrates bands, obviating adverse effects on the resolution of peak shape of the components of interest. The vaporizing chamber is interposed between a packed or wall-coated open tubular liquid chromatographic column and a gas chromatographic column. The liquid column permits the use of small volumes of eluent and reduced flow rates.
