IONIZATION MASS SPECTROMETER, ANALYTICAL METHOD, AND INSTRUMENTATION SYSTEM USING IT

摘要

PROBLEM TO BE SOLVED: To provide an ion source using corona discharge efficiently ionizing a sample. SOLUTION: In corona discharge producing at the tip of a needle electrode by applying high voltage, by almost facing the introduction direction of the sample to the area of the corona discharge and ion drawing out direction in the corona discharge, ion producing efficiency is enhanced.
