Identification of ions from MALDI TIMS by precursor ion fragmentation and product ion scan. A thin section from the ovarian tumor in Fig. 3 was analyzed using a hybrid quadrupole time-of-flight mass spectrometer (ABI Q-STAR) in negative ionization mode with selection of the shown parent ions for fragmentation and analysis of the product ion spectra. (A and B) Product ion spectrum for each compound (m/z 778.6 ion was identified as a d18:1/C16:0 ceramide monohexosylsulfatide and m/z 885.6 was most consistent with the shown phosphatidylinositol).
