ESI mass spectrometry

Use

Electrospray ionization (ESI) ESI mass spectrometry is a particularly versatile method because one can inject solutions directly into the mass spectrometer.
itThe study of unsubstituted and disubstituted beta-cyclodextrins (beta-CDs) by ESI-mass spectrometry is reported, applying a cone-induced fragmentation in the presence of a twofold excess of sodium chloride, in order to gain information about the fragmentation of the different regioisomers.
In this seminar, examples of how ESI mass spectrometry is being used in biomedical research will be presented.
Low-flow ESI mass spectrometry is being used to both identify and also to quantify levels of endogenous and exogenous opioids in urine and blood plasma samples; levels of individual peptides are being compared between healthy control subjects and autistic subjects.
ESI mass spectrometry is used to study compounds in solution and has become the most effective method for determining the molecular weight of inorganic and organometallic compounds [6].
