Tetraalkylammonium halides as chemical standards for positive electrospray ionization with ion mobility spectrometry/mass spectrometry.

Rapid Communications in Mass Spectrometry, 2005
Chemical standards for positive ion mode electrospray ionization ion mobility spectrometry/mass spectrometry (ESI(+)-IMS/MS) are suggested. The low clustering tendency of tetraalkylammonium halides makes them ideal chemical standards for ESI(+)-IMS/MS. A

[21] Electrospray ionization mass spectrometry

1996
Publisher Summary An electrospray ionization source operating at atmospheric pressure was first interfaced to a mass spectrometer in Fenn's laboratory at Yale University (New Haven, CT), with inspiration taken from earlier ion-stopping potential studies, using electrospray ionization conducted by Mack et al .

Miniaturization of Electrospray Ionization Mass Spectrometry

Applied Spectroscopy Reviews, 2003
1. Abstract The development of electrospray ionization (ESI) has proved an enormous breakthrough in structural biology because it provides a means for transferring large biological molecules into the gas-phase as intact charged ions. In the post-genomics era, increased attention has been focused on mass spectrometry techniques capable of providing ...

Arc-Induced Electrospray Ionization Mass Spectrometry

Analytical Chemistry, 2023
Arc-induced electrospray ionization mass spectrometry (AESI-MS) was developed during which alternating current electrospray is simply achieved through the arc plasma. The AESI source exploits the arc's temperature and charge properties to generate aerosols consisting of charged microdroplets.

Electrospray Ionization Mass Spectrometry: A Powerful Platform for Noble-Metal Nanocluster Analysis.

Angewandte Chemie, 2019
Electrospray 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.

[22] Electrospray ionization mass spectrometry

1990
Publisher Summary This chapter discusses electrospray ionization mass spectrometry. Electrospray ionization (ESI) occurs during the electrostatic nebulization of a solution of charged analyte ions by a large electrostatic field gradient (approximately 3 kV/cm). Highly charged droplets are formed in a dry bath gas, at near atmospheric pressure.
