Abstract
A method of mass analysis using a multi-turn time-of-flight mass spectrometer starts with recording plural heterogeneous turn number spectra F1(t), F2(t), . . . , Fq(t) containing plural ion peaks that might be different in number of turns, the spectra being obtained with different ion residence times taken from entry to departure using a multi-correlation function for reconstructing a single turn number spectrum.
