Electrospray ionization mass spectrometry of
Journal of the American Society for Mass Spectrometry, 2000 Lysoglycerophosphocholine lipids (lyso-GPC) are important intermediates in the synthesis and metabolism of glycerophosphocholine lipids which are major components of the cellular lipid bilayer. Significant differences in the collisional induced decomposition (CID) behavior were observed for each of the four different subtypes of lyso-GPC in both ...

Ionization and transmission efficiency in an electrospray ionization—mass spectrometry interface [PDF]
Journal of the American Society for Mass Spectrometry, 2007 The ionization and transmission efficiencies of an electrospray ionization (ESI) interface were investigated to advance the understanding of how these factors affect mass spectrometry (MS) sensitivity. In addition, the effects of the ES emitter distance to the inlet, solution flow rate, and inlet temperature were characterized.

Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Timely detection of microscopic tumors is of utmost importance in cancer diagnostics. We show that desorption electrospray ionization mass spectrometry imaging (DESI-MSI) can successfully locate microscopic aggregates of a common skin cancer,

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]
, 2015 Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

Recent advances in experimental techniques to probe fast excited-state dynamics in biological molecules in the gas phase : dynamics in nucleotides, amino acids and beyond [PDF]
, 2013 In many chemical reactions, an activation barrier must be overcome before a chemical transformation can occur. As such, understanding the behaviour of molecules in energetically excited states is critical to understanding the chemical changes that these ...

Probing Cyanocuprates by Electrospray Ionization Mass Spectrometry [PDF]
Organometallics, 2010 Solutions of CuCN/(RLi)n (n = 0.5, 0.8, 1.0, and 2.0 and R = Me, Et, nBu, sBu, tBu, and Ph) in tetrahydrofuran are analyzed by electrospray ionization mass spectrometry. In all cases, organocuprate anions are observed, whose exact nature depends on the reagent stoichiometry.
