Abstract: The invention provides a method for acquiring fragment ion spectra of substances in complex substance mixtures wherein a trapped ion mobility spectrometer (“TIMS”) is used as the ion mobility separator separation device. The fragment ion spectra may be used for the identification of high numbers of proteins in complex mixtures, or for a safe quantification of some substances, by their fragment ion mass spectra in a mass spectrometer with up-front substance separator. TIMS with parallel accumulation provides the unique possibility to prolong the ion accumulation duration to find more detectable ion species without decreasing the measuring capacity for fragment ion mass spectra. The high measurement capacity for fragment ion mass spectra permits the repeated measurement of low abundance ion species to improve the quality of the fragment ion spectra.
