| Research Abstract |
Chemical ionization(CI) mass spectrometry allows high-sensitive and real-time analysis of volatile organic compounds without decomposition, which are widely used under field measurements. A subject of current CI techniques is not to find reactant ions for ionization of acidic(in) organic compounds. In this study, I have established an ion source leading to the regular formation of reactant ions suitable for the ionization of acidic organic compounds having nitro and amino groups, using an accurate corona discharge system. The results obtained would contribute toward the identification and quantitative analysis of unknown nitro organic compounds in diesel vehicle exhausts.
