atmospheric pressure chemical ionisation

CHEMISTRY 

A method of mass spectrometry ionisation, in which an aerosolised sample is sprayed at atmospheric pressure into a heated region where a metal pin held at a high electric potential sustains a corona discharge.

The solvent discharge creates reagent ions that react with neutral sample molecules, resulting in protonated ions, which then pass through a sampling aperture into the spectrometer’s mass analyser.
