Current Role of Mass Spectrometry in the Determination of Pesticide Residues in Food

Separations, 2022
The extensive use of pesticides represents a risk to human health. Consequently, legal frameworks have been established to ensure food safety, including control programs for pesticide residues.

Monitoring Conformational Changes of Lysozyme–Polyelectrolyte Complexes Using Trapped Ion Mobility-Mass Spectrometry (IM-MS)

Analytical Letters, 2023
The conformational changes of lysozyme due to the formation of its complexes with polystyrene sulfonate (PSS) oligomers were monitored at different charge states using trapped ion mobility spectrometry-time-of-flight mass spectrometer (TIMS-TOF-MS). The mixtures of disulfide-intact lysozyme and PSS oligomers were directly infused into the ESI source of

Gas-phase microsolvation of ubiquitin: investigation of crown ether complexation sites using ion mobility-mass spectrometry. [PDF]

, 2016
In this study the gas-phase structure of ubiquitin and its lysine-to-arginine mutants was investigated using ion mobility-mass spectrometry (IM-MS) and electron transfer dissociation-mass spectrometry (ETD-MS).

Shotgun ion mobility mass spectrometry sequencing of heparan sulfate saccharides [PDF]

, 2020
Despite evident regulatory roles of heparan sulfate (HS) saccharides in numerous biological processes, definitive information on the bioactive sequences of these polymers is lacking, with only a handful of natural structures sequenced to date.

Recommendations for reporting ion mobility Mass Spectrometry measurements [PDF]

, 2019
Here we present a guide to 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 of mobility and collision ...

Combining density functional theory (DFT) and collision cross-section (CCS) calculations to analyze the gas-phase behaviour of small molecules and their protonation site isomers [PDF]

, 2016
Electrospray ion mobility-mass spectrometry (IM-MS) data show that for some small molecules, two (or even more) ions with identical sum formula and mass, but distinct drift times are observed.

IR ion spectroscopy in a combined approach with MS/MS and IM-MS to discriminate epimeric anthocyanin glycosides (cyanidin 3-O-glucoside and -galactoside) [PDF]

, 2019
Anthocyanins are widespread in plants and flowers, being responsible for their different colouring. Two representative members of this family have been selected, cyanidin 3-O-β-glucopyranoside and 3-O-β-galactopyranoside, and probed by mass spectrometry ...
