Patent ID: 11940426

Abstract:
Provided is a chromatograph mass spectrometer that includes a component separation unit 13 that temporally separates components in a sample, a first detector 15 that acquires measurement data of components included in an outflowing liquid from the component separation unit 13 by an analysis method different from mass spectrometry, a mass spectrometer 2 that acquires mass spectrometry data including intensity information for each of mass-to-charge ratios of ions derived from the components contained in the outflowing liquid from the component separation unit 13, a chromatogram creation unit 45 that creates a chromatogram representing an intensity change of the measurement data with time based on the measurement data of the first detector 15, an information extraction unit 46 that detects a peak based on the intensity change of the mass spectrometry data with time, and extracts information including a representative time of the peak, and a chromatogram display unit 48 that displays the chromatogram together with additional information corresponding to the extracted time.
