Data processing system

A chromatograph system comprising a processor and a data memorizing device and configured to process a three-dimensional chromatogram, obtained by chromatography analysis, including chromatogram data and a spectrum, wherein

• the data memorizing device is configured to memorize original data of the three-dimensional chromatogram and a maximum number of estimated peak components for analyzing the original data,
• the processor is configured to execute peak estimation processing of estimating peaks included in a peak waveform portion, formed by overlapping a plurality of peaks, of the original data by repeating a peak estimation step,
• the processor is configured, in the peak estimation processing, to fit the peak waveform portion with a function by assuming a number of components included in the peak waveform portion to estimate peak shapes for the number of components, and to execute a judging step of judging whether the number of components is less than the maximum number of estimated peak components,
• in a case where it is judged by the judging step that the number of components is less than the maximum number of estimated peak components, the processor is configured to (i) synthesize the estimated peak shapes to form a synthesized peak shape, (ii) subtract the synthesized peak shape from the chromatogram waveform to calculate a difference between the synthesized peak shape and the peak waveform portion, and (iii) compare the difference with a threshold value,
• in a case where the difference is greater than or equal to the threshold value, the processor is configured to increase the number of components by one and re-execute the peak estimation step,
• in a case where it is judged by the judging step that the number of components is greater than or equal to the maximum number of estimated peak components of the difference is less than the threshold value, the processor is configured to
• execute (i) a quantifying step of quantifying concentration of the peak components by calculating areas of the estimated peak shapes and (ii) display a result of the quantifying step on a display after the peak estimation processing is finished.
