Quantitative analysis combining high performance liquid chromatograph and mass spectrometer

摘要

A quantitative analyzing apparatus including a high- performance liquid chromatograph, a mass spectrometer, and an atmospheric pressure chemical ionization interface for linking the liquid chromatograph to the mass spectrometer to each other, wherein the interface includes an ionization chamber housing a corona discharge electrode. According to the present invention the electrode is comprised of a material selected from the group consisting of a silver alloy and a non-plated iron, and thereby quantitative analysis of organic compounds may be carried out.
