特定気体のコロナ放電により生成されるイオンと試料分子の反応に関する研究
Atmospheric pressure chemical ionization (APCI) is a versatile method suitable for ionizing gaseous molecules under atmospheric pressure conditions and is frequently used for ambient mass spectrometry. However, it is difficult to clarify the ion-molecule reactions in air corona discharge because the atmosphere contains various gas molecules such as nitrogen, oxygen, carbon dioxide, argon, and water vapor. In this study, the ion-molecule reactions of the regent ions produced by corona discharges under specific gas atmospheres have been investigated using a cylindrical discharge device constructed in our laboratory. Organic solvents such as ethanol, methanol, hexane, cyclohexane, toluene, and benzene were used as samples. H abstraction by CO3− was observed for hexane, cyclohexane, methanol, ethanol, and toluene, but no reactions were observed for benzene.
