A data storage section stores LC/MS analysis data for a large number of culture-medium samples acquired with an LC-MS. Based on those data, a quantitative analyzer calculates concentration values of a large number of compounds in each sample and stores the result in an analysis result storage section. A result display processor retrieves analysis results with the same culture name and different sampling date from the analysis result storage section, creates a table in which concentration values are arranged for each compound and for each sampling date, as well as a graph showing a temporal change in the concentration value of one compound, and displays the table and graph on the same window on a display unit. An operator using an operation unit selects a compound on the displayed table. The result display processor creates a graph for the selected compound and renews the graph on the display.
