Abstract:
1. A chromatograph analyzing device, comprising: a chromatograph unit for separating a component included in a sample; and a data processing device configured to identify the component in the sample by using chromatograph data obtained from the chromatograph unit and measuring the components mass and amount in the sample according to a calculation process, wherein: the data processing device is configured to execute a base line setting process on an unseparated peak appearing in the chromatograph data according to base line setting conditions set in advance so as to execute the calculation process on a waveform subject to the base line setting process, the base line setting conditions include a sample waveform which expresses a waveform of the unseparated peak expected to appear in the chromatograph data and a separating method for separating the sample waveform into two waveforms, in the base line setting process, a plurality of sample waveforms which are approximate to the unseparated peak appearing in the chromatograph data are selected, the selected sample waveforms are separated into two waveforms by the separating method, and the calculation process is executed on the two waveforms, the separating method includes an automatic separating method, and the automatic separating method includes at least one of Exponentially Modified Gaussian (EMG) model fitting, spline function approximation and normal distribution approximation.
