Patent ID: 7640117

Claim:
A chromatograph analyzing device comprising: a separation unit for separating a component included in a sample, a data processing device for identifying the component in the sample and the quantity of the component in the sample by using a chromatogram obtained from the separation unit, and; a storage device for saving a base line setting condition including at least a sample waveform and at least an unseparated peak separating method for separating an unseparated peak of the chroinatograph into two peaks, wherein the data processing device executes a base line setting process using the base line setting condition saved in the storage device, to compare the detected unseparated peak with at least a sample waveform saved in said storage device, to select a plurality of sample waveforms which are determined to be approximate to the unseparated peak or a sample waveform which is determined to be the most approximate to the unseparated peak, to separate each selected sample waveform into two peaks using the specified separating method saved in the storage device, and to calculate the areas of the two peaks of each separated sample waveform.
