  • Patent number: 11567047
    Abstract: A chromatographic data system processing apparatus includes a standard sample time table for prestoring a first retention time and a first allowable width of each peak of specific components of a standard sample, a determination unit for determining whether a number of peaks coincides with a specified number when a peak cannot be identified, an alteration unit for altering the standard sample time table by increasing the first allowable width of a specific component to an altered allowable width, an identification unit for identifying the peaks based on the altered standard sample time table when all peaks fall within a range of the altered allowable width, and a setting unit for acquiring an actually-measured retention time of the peaks, and setting a measurement sample time table based on the actually-measured retention time and a second allowable width when the peaks are identified based on the altered standard sample time table.

  • Publication number: 20180284080
    Abstract: A liquid chromatograph apparatus being unitary, enables to measure two or more varieties of measurement samples. The liquid chromatograph apparatus a single sample solution injection portion configured to inject a sample solution containing the measurement samples, a single liquid delivering system configured to deliver the injected sample solution, at least one measurement element out of an eluent tank, a separation column, and a detector, which configures a set of elements separately provided for each of the measurement samples, and a flow path switching portion configured to selectively connect the liquid delivering system with one element of the measurement element to be capable of delivering the sample solution.
