Coupling corona discharge for ambient extractive ionization mass spectrometry
The Analyst, 2011Unlike the extractive electrospray ionization (EESI) technique described elsewhere, a corona discharge instead of electrospray ionization has been utilized to charge a neutral solvent spray under ambient conditions for the generation of highly charged microdroplets, which impact a neutral sample plume for the extractive ionization of the analytes in ...

Chemical Aspects of the Extractive Methods of Ambient Ionization Mass Spectrometry
Annual Review of Physical Chemistry, 2013Ambient ionization techniques allow complex chemical samples to be analyzed in their native state with minimal sample preparation. This brings the obvious advantages of simplicity, speed, and versatility to mass spectrometry: Desorption electrospray ionization (DESI), for example, is used in chemical imaging for tumor margin diagnosis.

Switched Ferroelectric Plasma Ionizer (SwiFerr) for Ambient Mass Spectrometry
Analytical Chemistry, 2010We present the implementation of a switched ferroelectric plasma ionizer (SwiFerr) for ambient analysis of trace substances by mass spectrometry. The device utilizes the ferroelectric properties of barium titanate (BaTiO(3)) to take advantage of the high electric field resulting from polarization switching in the material.

Ambient ionization mass spectrometry as a tool for organic reaction tracking
Analytica Chimica ActaThermal desorption electrospray ionization mass spectrometry (TD-ESI/MS) is an ambient ionization technique that enables the rapid analysis of chemical compounds in solids or solutions. A small amount of the sample solution was placed onto a metal wire, and an electric current was applied to heat it quickly.
