Trapped ion mobility spectrometry (TIMS) is a relatively new gas-phase separation method that has been coupled to quadrupole orthogonal acceleration time-of-flight mass spectrometry. Ion mobility-mass spectrometry (IM-MS) combines complementary size- and mass-selective separations into a single analytical platform. This chapter provides context for both the instrumental arrangements and key application areas ion mobility spectrometry that are commonly Fundamental questions in ion mobility spectrometry have practical implications for analytical applications in general, and omics in particular, in three respects. (1) Understanding how ion mobility and collision cross section values depend on the collision gas, on the electric field and on temperature is crucial to ascertain their transferability across instrumental platforms.

Abstract Trapped ion mobility spectrometry (TIMS) hybridized with mass spectrometry (MS) is a relatively recent advance in the field of ion mobility mass spectrometry (IMMS). The basic idea behind TIMS is the reversal of the classic drift cell analyzer.
