  • Liquid chromatograph and method for correcting detector output value fluctuation of liquid chromatograph
    Patent number: 10935526
    Abstract: A minimum peak is determined from analysis results, a correction wavelength at which an S/N ratio of the minimum peak is greatest is determined, and the determined correction wavelength is used to execute correction of the minimum peak. A plurality of detector output value correction method are registered in a processor, correction method is selected from default correction method or from among a plurality of preset correction methods according to an object to perform correction.
    Type: Grant
    Filed: December 16, 2019
    Date of Patent: March 2, 2021
    Assignee: HITACHI HIGH-TECH SCIENCE CORPORATION
    Inventors: Shuhei Yamamura, Daisuke Akieda, Ayumi Nakaogami, Katsutoshi Shimizu
