ABSTRACT:
The present invention relates to a method and apparatus for chromatographically analyzing each of a plurality of samples in detector, comprising an autosampler to contain a plurality of samples for chromatographic analysis and a plurality of chromatographic systems, each system comprising one or more pumps and one or more chromatography columns. A detector is included for detecting compounds in the samples from each of the chromatography systems along with a valve positioned between the detector and the plurality of chromatography systems, the valve permitting each sample to reach the detector in sequence. A computer control device is included which adjusts the introduction of samples from the autosampler into the plurality of chromatography systems as well as the position of the valve to sequentially separate and deliver compounds within the samples to the detector.
