Electrospray Ionization-Induced Protein Unfolding [PDF]
Journal of the American Society for Mass Spectrometry, 2012 Electrospray ionization mass spectrometry (ESI-MS) measurements were performed under a variety of solution conditions on a highly acidic sub-fragment (B3C) of the C-terminal carbohydrate-binding repeat region of Clostridium difficile toxin B, and two mutants (B4A and B4B) containing fewer acidic residues.

Principles of Electrospray Ionization [PDF]
Molecular & Cellular Proteomics, 2011 Electrospray ionization is today the most widely used ionization technique in chemical and biochemical analysis. Interfaced with a mass spectrometer it allows the investigation of the molecular composition of liquid samples. With electrospray a large variety of chemical substances can be ionized.

Some Thoughts on Electrospray Ionization Mechanisms
European Journal of Mass Spectrometry, 2011 Electrospray ionization (ESI) mechanisms are highly complex, due to a series of physical and chemical phenomena taking place on a complex system, as a solution is. In fact, even if the solution of an analyte in a protic medium can be considered at first sight to be a two-component system, the presence of solvent dissociation ...

Transmission mode desorption electrospray ionization [PDF]
Journal of the American Society for Mass Spectrometry, 2008 A new mode of operation for desorption electrospray ionization (DESI) analysis of liquids or solid residues from evaporated solvents is presented. Unlike traditional DESI, the electrospray is not deflected off of a surface but instead is transmitted through a sampling mesh at a 0 degrees angle between the electrospray tip, sample mesh, and capillary ...

Nanobubbles in Electrospray Ionization Mass Spectrometry. [PDF]
Anal ChemNanobubbles (NBs) are very small gas-filled cavities in solvents, and when their sizes reach diameters around 200 nm, they remain in solution for extended periods of time, featuring special chemical and physical properties. Here, we investigate the application of NBs in electrospray ionization.

Mechanistic investigation of ionization suppression in electrospray ionization [PDF]
Journal of the American Society for Mass Spectrometry, 2000 We show results from experiments designed to determine the relative importance of gas phase processes and solution phase processes into ionization suppression observed in biological sample extracts. The data indicate that gas phase reactions leading to the loss of net charge on the analyte is not likely to be the most important process involved in ...
