Abstract
The measurement throughput and the precision in sample identification are improved in a tandem type mass spectrograph. Thus, in a mass spectrum analyzing system utilizing a tandem type mass spectrograph in which the selection of an ionic species to serve as the measurement target, dissociation thereof and spectral measurement are repeated in n stages, the ionic species to be measured in MSis selected based on the mass-to-charge ratios (m/z values) obtained as a result of the spectral analysis in MS(n≧2), and this procedure is repeated until the sequence of a required number of amino acids is determined.
