(a) The MPT mass spectrum of lanthanum collected on the MPT-LTQ-MS in positive mode. A 10 mg/L lanthanum standard solution was used. (b) mass spectra of the precursor ions 317, up to 6. The subprecursor ions series are , corresponding to the dissociation fragment series H2O, H2O, H2O, NO, and NO4. (c) The MPT mass spectrum of La collected on a MPT quadrupole mass filer mass spectrometer.
