Electrospray ionization mass spectrometry (ESI-MS) is an analytical method for mass determination of ionized molecules. It is a commonly used method for soft ionization of peptides and proteins in quadmpole, ion-trap, or time-of-flight mass spectrometers. The ionization is performed by application of a high voltage to a stream of liquid emitted from a capillaty. The highly charged droplets are shrunk and the resulting peptide or protein ions are sampled and separated by the mass spectrometer.

Mass spectrometry is a useful tool to detect the existence of reactive iron-imido intermediates. In intramolecular aromatic aminations, Que and coworkers used electrospray ionization mass spectrometry to show the presence of a molecular ion at m/z 590.3 and 621.2, which could be attributed to the formation of [(6-(o-TsN-C6H4)-TPA)Fe ]+ and [(6-(o-TsN-C6H4)-TPA)Fe° OMe)]+. With the isoto-...

The fenoxycarb recoveries for orange, onion, grape, and tomato samples ranged from 63 to 70%. The LOQ and LOD were 0.01 mg kg and 0.005 mg kg , respectively, when using liquid chromatography/electrospray ionization mass spectrometry (LC/ESI/MS). 

On the other hand, electrospray ionization mass spectrometry (ESMS) has been first combined with electrochemistry at ITIES in order to confirm the stoichiometry of a complex ion transferred into an organic phase directly. ESMS is now becoming a popular and powerful technique not only in chemistry but also in biology, pharmacy, medical science, etc. Electrospray (ES) ionization is exceedingly effective resource for producing gas-phase ions from various solutions which contain any kinds of ion. Thus, ESMS can sometimes give us highly useful information in comparison with electrochemical results.
