Chromatographic mass spectrometry method and chromatographic mass spectrometry apparatus

摘要

A chromatographic mass spectrometry method capable of detecting a peak that can correspond to a wide concentration range of a sample component and providing an evaluation value for the result is realized. Multiple samples of known components with different concentrations are measured to detect the start, apex, and end points of the peak (steps 101-1 and 101-2). For the start point, apex, and end point of the detected peak, the score function is determined by using the evaluation value such as the certainty as the score (step 101-3). The start point, apex, and end point of the peak are detected by measuring the component whose concentration is unknown (steps 102-1 and 102-2). For the start point, apex, and end point of the detected peak, the score function is applied to evaluate the peak detection result, and the one with the highest evaluation is selected as the peak (step 102-3).
