Ion mobility spectrometry (IMS) is an electrophoretic technique that allows ionised analyte
molecules to be separated on the basis of their mobilities in the gas phase. The technique …

Steroids are an important class of biomolecules studied for their role in metabolism,
development, nutrition, and disease. Although highly sensitive GC-and LC-MS/MS-based …

The analytical power of ion mobility spectrometry-mass spectrometry (IMS-MS) instruments
is poised to advance this technology from research to analytical laboratories. Exploring …

Structural information of gas phase complexes of poly (ethylene glycol)(PEG) cationized by
one or two different alkali metal ions is inferred from MS and MS/MS experiments performed …

Gas-phase ion mobility studies of mixtures containing polyethylene glycols (PEG) and an
active pharmaceutical ingredient (API), lamivudine, have been carried out using …

The non-covalent complexes formed between cyclic (eg, 12-crown-4 (12C4), 15-crown-5
(15C5), and 18-crown-6 (18C6)) and acyclic (eg, triglyme and tetraglyme) polyethers with …

A nano-electrospray ionisation source has been designed and constructed for a high
temperature ion mobility spectrometer. The drift cell was modified by replacement of the …

Quaternary ammonium salts (Quats) and amines are known to facilitate the MS analysis of
high molar mass polyethers by forming low charge state adduct ions. The formation, stability …

A systematic evaluation of the intermolecular binding forces responsible for the association
of crown ethers (hosts) with alkyl amines (guests) is presented by exchanging the …
