FIELD: chemistry.
SUBSTANCE: invention can be used to ionize molecules. Invention consists in that an electrical ionization source includes a wire that is looped between electrical contacts. The wire is used to form a corona responsive to application of voltage between the wire and the walls of an ionization chamber. Corona can form when a sufficient voltage is applied between the wire and the walls. Difference in electrical potential between the wire and a wall forming an ionization chamber, in which wire is contained, can be used to draw the ions away from the wire. In embodiments, the wire can be heated to reduce the voltage used to strike the corona.
EFFECT: technical result is possibility of ionisation of molecules from the samples of interest to identify molecules on the basis of ions.
