Abstract
According to the existing mass spectrometric system, whether or not the informations are sufficient for analyzing substances (particularly proteins, sugars, etc.) cannot be judged in the process of measurement. Further, it is difficult to find out isomers having just the same mass number or compounds very close in mass only from the MS data. According to this invention, whether or not the retention time in the LC (or GC) of peptide formed at the time of enzymatic decomposition of protein coincides with the predicted retention time assumed from the amino acid sequence predicted from MSmass spectrometry data is judged within the actual time period of measurement, and thereby the quality of MSmass spectrometry data (quantity of information) is judged.
