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.

Abstract: In a chromatographic analyzer which performs a measurement on multiple compounds for each of the multiple samples, a data-analysis processor calculates, for each sample, multiple pieces of numerical information obtained by data analysis on multiple compounds, based on measurement data. A table creator creates a two-dimensional table by arranging sample identifier in one direction of the table and compound identifier in the other direction, and assigning numerical information obtained for a combination of one sample and one compound to a cell of the table corresponding to the combination. A cell selection receiver displays the table on a display screen and receives a selection of a cell or cells according to a user operation on the displayed table. A selected information outputter outputs or displays the numerical information in the selected cell(s) in a predetermined format along with the sample and compound identifiers corresponding to the cell(s).

Abstract: Sequential identification numbers are automatically provided and undisplayed, constant, unique numbers are assigned to each event registered in an analysis condition setting table 100. Since correspondence information between the identification numbers and the unique numbers changes due to the reassignment of identification numbers when an event is deleted from the table, event identification numbers for each compound are changed by referring to the correspondence information on a compound information table. As a result, it is possible to avoid the misalignment of event identification numbers between both tables. In addition, when an instruction is given to coordinate the time information or m/z information on both tables, the information on one table is reflected on the other table in accordance with the identification numbers.
