Hyphenated Applications of Mass Spectrometry for the Analysis of Biological Compounds [PDF]
, 2012 A variety of hyphenated mass spectrometry techniques were implemented for the analysis of biological compounds. Ion mobility combined with mass spectrometry was used to measure gas-phase conformations of proteins sprayed from slightly alkaline solutions.

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.

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.
