Electrospray Ionization Experts

The following experts are available as electrospray ionization consultants and electrospray ionization expert witnesses.  ORC experts are peer-recommended authorities who have been carefully selected and rigorously screened.
    Definition:  Electrospray Ionization - A technique used in mass spectroscopy in which the sample is injected into the spectrometer by means of an electrostatically charged stream, pumped directly from a chromatograph, which allows the continual monitoring of a sample over an extended period. This form of spectroscopy is best used for identifying the mass of larger molecules, like proteins.

Synonyms:  electrospray ionisation, electrospray ionization mass spectrometry, electrospray linked mass spectrometry, electrospray mass spectrometry, ESI, ESI-MS, ES-MS
