A method of mass spectrometry comprises: a) separating first ions or components of an analyte sample according to a physicochemical property other than ion mobility, e.g. by chromatography; b) separating the first ions or second ions formed from the components according to ion mobility; c) detecting the intensities of the first ions, the second ions formed from the components or ions, and recording the intensity of the ions detected at any given time together with an associated value of the physicochemical property and the ion mobility to obtain spectral data; d) examining the intensities of the spectral data as a function of the ion mobility to detect an intensity peak, determining a discrete value of ion mobility for the peak, and defining a window of values of ion mobility that encompasses the discrete value; and e) filtering the spectral data to include only spectral data that has been associated with values of ion mobility within the window of ion mobility values. The invention may enable data to be removed that may otherwise obscure or interfere with the intensity peaks displayed as a function of the physicochemical property (e.g. intensity vs. chromatographic retention time). |
