Abstract
A method of mass spectrometry is disclosed comprising isolating a group of different ions derived from chemical compounds in the same class, wherein the different ions have different mass to charge ratios and ion mobilities. The step of isolating comprises temporally separating the ions according to their ion mobility in an ion mobility separator; and mass filtering the ions according to mass to charge ratio with a mass filter. The mass to charge ratios transmitted by the mass filter are varied as a function of time such that said different ions derived from chemical compounds in the same class are transmitted by the mass filter and other ions are not transmitted by the mass filter.
