DETERMINING THE REDUCED ION MOBILITY OF ION SPECIES BY TRAPPED ION MOBILITY SPECTROMETRY (TIMS)

摘要

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