IONIZATION METHOD, MASS ANALYSIS METHOD, EXTRACTION METHOD AND REFINING METHOD

摘要

PROBLEM TO BE SOLVED: To achieve soft ionization more easily when the minute amount of substance is ionized under an atmospheric pressure environment.;SOLUTION: An ionization method for substance contained in liquid includes the steps of: supplying the liquid from a probe to a substrate and forming a liquid bridge between the probe and the substrate with the liquid obtained by dissolution of the substance; vibrating the substrate; and forming an electric field between a conductive portion of the probe in contact with the liquid and an ion extraction electrode.;COPYRIGHT: (C)2013,JPO&INPIT
