Detection of explosives on skin using ambient ionization mass spectrometry

Chemical Communications, 2007
Single nanogram amounts of the explosives TNT, RDX, HMX, PETN and their mixtures were detected and identified in a few seconds on the surface of human skin without any sample preparation by desorption electrospray ionization (DESI) using a spray solution of methanol-water doped with sodium chloride to form the chloride adducts with RDX, HMX, and PETN ...

Ambient molecular imaging by desorption electrospray ionization mass spectrometry

Nature Protocols, 2008
Desorption electrospray ionization (DESI) allows the direct analysis of ordinary objects or pre-processed samples under ambient conditions. Among other applications, DESI is used to identify and record spatial distributions of lipids and drug molecules in biological tissue sections.

Coupling corona discharge for ambient extractive ionization mass spectrometry

The Analyst, 2011
Unlike 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, 2013
Ambient 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, 2010
We 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 Acta
Thermal 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.
