Abstract
In an ion mobility-mass spectrometry (IM-MS) system, an ion mass-isolated data set is acquired by operating a mass filter to apply a mass isolation window having an m/z width such that the mass isolation window moves through a sequence of window positions, each window position being defined by an IM drift time value and an m/z ratio value. The m/z width of the mass isolation window and the sequence of window positions are determined such that the mass isolation window captures ions in a region of interest of a larger all-ions data set. The isolation window may be a wideband isolation window. In comparison to the all-ions data set, the mass-isolated data set may yield reduced ion signal interference and increased selectivity for analytes of interest.
