Definition Of

Here we present a guide on ion mobility mass spectrometry experiments, which covers both linear and nonlinear methods: what is measured, how the measurements are done, and how to report the results, including the uncertainties on mobility and collision cross section values. The guide aims to clarify some possibly confusing concepts, and the reporting recommendations should help researchers, authors and reviewers to contribute comprehensive reports, so that the ion mobility data can be reused more confidently. Starting from the concept of the definition of the measurand, we emphasize that (i) mobility values (K0) depend intrinsically on ion structure, the nature of the bath gas, temperature, and E/N, (ii) ion mobility does not measure surfaces directly, but collision cross section (CCS) values are derived from mobility values using a physical model, (iii) methods relying on calibration are empirical (and thus may provide method-dependent results) only if the gas nature, temperature or E/N cannot match those of the primary method. Our analysis highlights the urgency of a community effort towards establishing primary standards and reference materials for ion mobility, and provides recommendations to do so. <br><br><br>

Rapid Resolution

Identifying small sugar isomers can be challenging by ion mobility-mass spectrometry (IM-MS) alone due to their small collision cross section differences.

First Time

Using collisional activation mass spectrometry the structures of the [M–HX]+• ions (X = OH, NH2) from 5-phenylpentanol-1 (1), 5-phenylpentylamine (2) and 6-phenylhexanol-1 (3) have been established. Contrary to previous results it is shown for the first time that in addition to ionized 1-phenyl-alkenes-1 some other double bound isomers as well as phenylcyclopentane and phenylcyclohexane are formed. The results strongly suggest that the HX eliminations are induced by a selective activation of CH bonds.
