Abstract:
1. A preparative liquid chromatograph (LC) system comprising: an LC unit including a column for isolating a component in a sample and a detector for detecting the component in an eluate from the column; a fraction collector for fractionating the eluate and separating each fraction of the eluate in individual containers; a preparative separation execution controller for controlling the LC unit and the fraction collector to separate a single target component in a predetermined sample into a plurality of individual containers per a predetermined fractionation time; an individual LC execution controller for controlling the LC unit to perform an LC analysis and obtain a chromatogram individually on the single target component separated in each of the plurality of containers; a peak data calculator for deriving a peak data from a single component suctioned from different containers, corresponding to the amount of the single target component on each of the chromatograms; and a calculation processor for estimating delay data on a delay from detection of a component in the eluate with the detector to separation of the component with the fraction collector, by using at least a peak data corresponding to a maximum amount of the single target component and its previous and succeeding peak data on a time axis obtained by the peak data calculator.
