Abstract
A spectroscopic detector includes a light source, a flow cell, a diffraction grating, a diffraction grating drive unit, an optical sensor and a diffraction grating position adjustment unit. The diffraction grating drive unit is configured to adjust a rotation position of the diffraction grating within a range that light of a specified wavelength region of plus side diffracted light and light of the specified wavelength region of minus side diffracted light among diffracted light caused by the diffraction grating is selectively guided to the flow cell. The diffraction grating position adjustment unit is configured to adjust the rotation position of the diffraction grating unit in order to selectively guide one of the light of the specified wavelength region of the plus side diffracted light and the light of the specified wavelength region of the minus side diffracted light among the diffracted light caused by the diffraction grating.
