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 ...

An Organic Chemist’s Guide to Electrospray Mass Spectrometric Structure Elucidation
Molecules, 2019 Tandem mass spectrometry is an important tool for structure elucidation of natural and synthetic organic products. Fragmentation of odd electron ions (OE+) generated by electron ionization (EI) was extensively studied in the last few decades, however ...

Mechanistic investigation of ionization suppression in electrospray ionization
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 ...
