PURPOSE:To accurately perform the simultaneous analysis of a plurality of components having different max. absorption wavelengths, by providing a control mechanism capable of performing the wavelength change-over setting of a detected optimum UV wavelength to the required component from a separation column on the holding time thereof by an UV detector. CONSTITUTION:A liquid chromatograph apparatus 1 is constituted of a flow passage formed of a moving phase storage tank 2, a high pressure liquid feed pump 3, a specimen injection part 4, a separation column 5 equipped with a thermostatic tank 51 and the flow cell set in an UV detection part. The UV detection part is constituted of an optical system equipped with a deuterium lamp 12, a slit 13, a diffraction lattice 10, a concave mirror 14, a slit 15 and a photomultiplier tube. The diffraction lattice 16 is adjusted in its angle by a stepping motor 11. The change-over of a wavelength suitable for each component is performed by said optical system, a control part 18, an injection detection sensor 41 and a key input part 9 to perform accurate analysis. |
