Claim Text:
1. A chromatography system comprising: a flow cell to which a specimen is supplied; optics that directs light to the flow cell and outputs light that has passed through the flow cell, the optics having a function of wavelength dispersion of light; a multi-channel detector disposed at an output side of the optics, that receives respective wavelengths of the light dispersed by the optics; and a signal processing circuit provided in connection with the detector that obtains a chromatogram based on an intensity of light having a measuring wavelength to be measured that has been outputted from the detector, wherein the signal processing circuit corrects a baseline of the chromatogram based upon an average of intensities of light having a plurality of wavelengths that are detected simultaneously with the measuring wavelength and are longer than the measuring wavelength, wherein when correcting the baseline, the signal processing circuit calculates an absorbance by where I is an intensity of light having a wavelength to be measured, and I0 is a reference intensity of light, the reference intensity of light is set based upon an average of intensities of light having a plurality of different wavelengths.
