Theoretical impact cross section ('CCS') in the experiment design

摘要

A method of mass spectrometry is disclosed, comprising: calculating an ion mobility value, collision cross-section, or interaction cross-section of a number of different analyte ions under one or more different analytical conditions; and determining one or more operating parameters of a mass spectrometer in response to the calculated ion mobility values, collision cross-sections, or interaction cross-sections; to maximize or enhance subsequent ion mobility separation of a number of different analyte ions.
