Chromatogram analysis apparatus

Abstract

A chromatogram analysis apparatus comprises a system information storage unit configured to store a system volume, which is a volume of piping through which a sample of a fluid chromatograph passes; an analysis information storage unit configured to store a chromatogram acquired by an analysis performed by the fluid chromatograph, flow rate information regarding a flow rate of a mobile phase during the analysis, and composition information regarding a composition of the mobile phase in each time period during the analysis; a time calculation unit configured to calculate a mobile phase arrival time, which is a time required for a mobile phase delivered from a liquid sending unit of the fluid chromatograph to reach a detector, and a sample arrival time, which is a time required for a sample injected into the mobile phase to reach the detector, based on the system information, the flow rate information, and the composition information; an analysis range determination unit configured to determine a target range for peak analysis on the chromatogram based on the mobile phase arrival time and the sample arrival time, such that a composition-derived peak, which is a peak caused by a rapid change in the composition of the mobile phase, and an injection-derived peak, which is a peak caused by the injection of the sample into the mobile phase, are excluded from the analysis target; and a peak analysis unit configured to execute the peak analysis within the analysis range determined by the analysis range determination unit.
