Abstract

The invention provides methods and devices for determining the reduced ion mobility Ko of an ion species by trapped ion mobility spectrometry wherein the reduced ion mobility Ko is determined from a measured arrival time tm of the ion species and predetermined instrumental parameters by applying the inverse of a system function: Ko=SYS−1(tm,pi) or from multiple arrival times tm,i of the ion species measured for multiple values of an instrumental parameter.
