Spectrum of all precursor ions that have undergone a selected m/z decrement corresponding to the mass of a particular neutral divided by the charge number of the precursor. The ions detected are the product ions produced by loss of a preselected neutral mass following collision-induced dissociation of the precursor ions in a collision cell.
