Abstract:
An apparatus for chromatographically analyzing each of a plurality of samples in a detector, comprising:(a) an autosampler to contain a plurality of samples for chromatographic analysis; (b) a plurality of chromatographic systems, each system comprising one or more pumps and one or more chromatography columns; (c) a detector for detecting compounds in said samples from each of said chromatography systems; (d) a valve positioned between said detector and said chromatography systems, said valve permitting each sample to reach the detector in sequence; and (e) a computer control device which adjusts the introduction of samples from said autosampler into said chromatography systems as well as the position of said valve to sequentially deliver said compounds in said samples to said detector, wherein each column contains one pump for loading sample and one pump for establishing a flow of eluant, wherein said computer control device contains input information concerning said samples for said chromatographic analysis regarding said samples anticipated arrival at said detector, and wherein said computer control device adjusts said introduction of sample from said autosampler as well as the position of said valve to sequentially deliver eluant to said detector.
