Abstract
A time-of-flight (ToF) mass analyser determines mass to charge ratio (m/z) of ions by determining flight times along an ion path. In first and second modes of operation, flight times of the ions along the ion path are determined to obtain respective first and second sets of data. In the first and second modes, the ion path has first and second path lengths and the paths are maintained at first and second pressures, respectively, wherein the first and second path lengths and/or the first and second pressures are different. An ion peak in the first set of data is compared to a corresponding ion peak in the second set of data, and a collision cross section of the associated ions is determined based on the comparison.
