Structure-drift Time Relationships In Ion Mobility Mass Spectrometry

open access: yes, 2015
Ion mobility spectrometry (IMS) separates ions while they travel through a buffer gas under the influence of an electrical field. The separation is affected by mass and charge but most particularly by shape (collision cross section).

Lithium Isotopic Analysis of Spodumene by Secondary Ion Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 13, 15 July 2026.
ABSTRACT Rationale Lithium (Li) stable isotopes can provide insight into fluid–rock interaction and magmatic differentiation. Therefore, it is essential to develop an accurate and precise method to determine the Li isotope signature in spodumene.

The potential of ion mobility spectrometry (IMS) for detection of 2,4,6-trichloroanisole (2,4,6-TCA) in wine

open access: yesTalanta, 2012
The off-flavor of "tainted wine" is attributed mainly to the presence of 2,4,6-trichloroanisole (2,4,6-TCA) in the wine. In the present study the atmospheric pressure gas-phase ion chemistry, pertaining to ion mobility spectrometry, of 2,4,6-trichloroanisole was investigated.

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

open access: yesMass Spectrometry Reviews, Volume 45, Issue 4, Page 599-623, July/August 2026.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.
