Abstract
PURPOSE:To add a material discriminating function to a detector of a chromatograph, by securing such constitution in which a pressure-sensitive element is provided to a sample cell to detect the periodical pressure change of a material contained in the sample cell which is caused by the intermittent light. CONSTITUTION:The light given from a light source L are made intermittent by a shutter S and made incident to a flow cell C through a filter F which absorbs the absorbed spectrum beam of a carrier fluid of a liquid chromatograph passes through the cell C. Then the periodical pressure change of the carrier fluid is detected by a microphone M. Thus a chromatograph is detected. The beams passed through the cell C are condensed on a slit XS through a condenser lens XL and then made incident to a convex diffraction grating G to be dispersed. Thus a spectrum image is formed on a solid-state image pickup element P. When the peak of the output is detected for the microphone M, the output of the element P is read to obtain the information on the sample component that produced the peak output.
