Abstract: Provided is a preparative separation liquid chromatograph system and preparative separation condition searching method which allows for an easy setting of the preparative separation condition. A sample temporally separated into components by a separation column is introduced into a detector and a fraction collector, with each component fractionated and collected by the fraction collector based on the result of a detection by the detector. A controlling and processing unit holds the following data for each sample or compound in the form of a database: chromatogram data obtained when a liquid chromatograph analysis in a preparative separation condition searching mode is performed for various standard samples under a search condition; and chromatogram data obtained when a liquid chromatograph analysis in a preparative separation mode is performed under one or more sets of preparative separation conditions for the various standard samples, along with the preparative separation condition used in this analysis.
