Abstract

A chromatograph analyzing device for automatically executing a base line setting process on an unseparated peak using preset base line conditions. The chromatograph analyzing device includes a separation unit for separating a component included in a sample, and a data processing device for identifying the component of the sample and the quantity of the component in the sample by using a chromatogram obtained from the separation.

Claims (11)

1. A chromatograph analyzing device comprising:

a chromatograph unit for separating a component included in a sample;

a data processing device for processing chromatograph data obtained from the chromatograph unit;

a display device for displaying the chromatograph data; and

a storage device for saving base line setting conditions as waveform processing conditions for an unseparated peak appearing in the chromatograph data,

wherein the base line setting conditions include a sample waveform which expresses a waveform of an unseparated peak expected to appear in the chromatograph data and a separation method using a base line specified by a user for the unseparated peak in the chromatograph data displayed on the display device, and

the data processing device, based on a comparison between a configuration of sample waveform saved in the storage device and a configuration of the unseparated peak in the chromatograph data, separates the unseparated peak using a base line specified by a user saved in the storage device by any of the separation methods selected by the user and saves a separated waveform prepared by the separation method in the storage device.

2. The chromatograph analyzing device according to claim 1 , wherein the data processing device uses the separated waveform prepared by the separation method, which is saved in the storage device, as the separation condition.

3. The chromatograph analyzing device according to claim 1 , wherein the separating method specified by the user includes a vertical line method, a forward horizontal line method, or a backward horizontal line method.

4. The chromatograph analyzing device according to claim 1 , wherein the common parameters are set for the separating method specified by the user.

5. The chromatograph analyzing device according to claim 1 , wherein the display device displays a setting process screen for setting a separating method to be specified by the user and the setting process screen has a separating method specifying field for specifying the separating method, a base line drawing method specifying field for specifying a base line drawing method, and a separated waveform parameter setting field for setting parameters common with the separating method.
