Abstract
When, in performing MS/MS analysis on a multivalent ion originated from a target component, an analyzing operator inputs at least two values of a mass value mof an eliminated fragment, a valence zof the eliminated fragment, a valence zof a precursor ion and a valence zof a product ion by an inputting unit, a valence calculating unit calculates an uninput valence zor zbased on the relation, z=z+z. Upon the start of the MS/MS analysis, a precursor ion m/z setting unit sets m/z=Mof an ion that passes through a front-stage quadrupole mass filter , and a passed product ion m/z calculating unit calculates m/z=Mof the product ion that passes through a rear-stage quadrupole mass filter by applying M, m, zand zabove to the relational expression, M=(M×z−m)/z.
