Unraveling the mechanism of electrospray ionization.
Analytical Chemistry, 2013Electrospray ionization (ESI) generates intact gas-phase ions from analytes in solution for mass spectrometric investigations. ESI can proceed via different mechanisms. Low molecular weight analytes follow the ion evaporation model (IEM), whereas the charged residue model (CRM) applies to large globular species.

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 Mass Spectrometry: A Powerful Platform for Noble-Metal Nanocluster Analysis.
Angewandte Chemie, 2019Electrospray ionization mass spectrometry (ESI-MS) is an analytical technique that measures the mass of a sample through "soft" ionization. Recent years have witnessed a rapid growth of its application in noble-metal nanocluster (NC) analysis.

On the Mechanism of Extractive Electrospray Ionization
Analytical Chemistry, 2010Extractive electrospray ionization (EESI) is a powerful ambient ionization technique that can provide comprehensive mass spectrometric (MS) information on aerosols, complex liquids, or suspensions without any sample pretreatment. An understanding of the EESI mechanism is critical for defining its range of application, the advantages, and limitations of

Rationale Although it is claimed that desorption electrospray ionization (DESI) causes less ion suppression effects than electrospray ionization (ESI), a related investigation with quantification measurement of ion suppression effects is absent.

Incorporation of a Venturi Device in Electrospray Ionization
Analytical Chemistry, 2003Electrospray ionization has grown to be one of the most commonly used ionization techniques for mass spectrometry, and efforts continue to improve its performance. Typically, the sprayer tip must be very close to the entrance orifice of the mass spectrometer in order to maximize the conduction of ions from the sprayer into the mass spectrometer ...

Probe electrospray ionization (PESI) is an electrospray-based atmospheric-pressure surface sampling and ionization technique for mass spectrometry that uses a solid needle instead of a capillary. While ionization occurs in a fashion similar to that involved in electrospray ionization, the novel aspect of PESI is discontinuous sampling.

Desorption electrospray ionization of aerosol particles
Rapid Communications in Mass Spectrometry, 2007Abstract We have applied desorption electrospray ionization to aerosol particles. Ions were formed from aerosols by merging suspended dry particles with an electrospray of solvent in a modified ion trap mass spectrometer. Dry aerosol particles were generated using a fluidized bed powder disperser and directed toward the inlet of the ...
