Efficiency of nano-electrospray ionization [PDF]
Journal of the American Society for Mass Spectrometry, 2005 The efficiency of nano-electrospray ionization, defined as the flux of ions reaching the detector of a triple-quadrupole mass spectrometer divided by the flux of analyte ions leaving the needle, has been measured in a series of controlled experiments with dodecyltrimethyl ammonium (DDTMA) bromide, myoglobin, Glu- [1]-fibrinopeptide, and gramicidin S ...

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.

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.

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 ...

Electrospray ionization of copper—glycine solutions [PDF]
Journal of the American Society for Mass Spectrometry, 1996 We have characterized the electrospray ionization (ESI) spectra of mixtures of the 3d transition metal ion Cu(2+) with both a model amino acid (glycine) and a simple peptide system (glycylglycine). We found what appear to be two major classes of ions.

Electrospray Ionization on Solid Substrates
Mass Spectrometry, 2014 Development of electrospray ionization on solid substrates (solid-substrate ESI) avoids the clogging problem encountered in conventional capillary-based ESI, allows more convenient sampling and permits new applications. So far, solid-substrate ESI with various materials, e.g., metals, paper, wood, fibers and biological tissue, has been developed, and ...
