Abstract
Provided is a method for quantitatively estimating the probability of substance identification based on the result of an MSanalysis using a certain MSpeak as the precursor ion, before performing the MSanalysis. Based on the result of MSand MSanalyses and substance identification performed for each of a number of fractionated samples obtained from a known preparatory sample, an identification probability estimation model creator grasps m/z and S/N ratios of MSpeaks having high probabilities of successful identification, calculates a parameter which determines the order of MSpeaks and a parameter representing an identification probability estimation model, and stores the parameters in a memory. When identifying a substance, an approximate order is calculated for an MSpeak obtained by the analysis. The identification probability for that peak is estimated from the approximate order with reference to the identification probability estimation model.
