記載の液体クロマトグラフ用分光器。[Claims for Utility Model Registration] 1. For liquid chromatographs in which light incident through the entrance slit 12A is reflected onto the diffraction grating 16A by the concave mirror 14, and the light reflected and diffracted by the diffraction grating is emitted from the output slit 18A. In the spectrometer, a center line of light incident on the diffraction grating and a center line of light reflected and diffracted by the diffraction grating and passing through the exit slit exist on the same plane substantially parallel to the ruled line direction of the diffraction grating. A spectrometer for liquid chromatography, characterized in that the entrance slit, the diffraction grating, and the exit slit are arranged so as to 2. The entrance slit, the diffraction grating, and the exit slit are arranged so that the opening center line of the entrance slit 12A, the rotational center axis Q of the diffraction grating 16A, and the opening center line of the exit slit 18A are approximately in the same plane. Claim 1 characterized in that a slit is arranged.
Spectrometer for liquid chromatography as described.
