LC分離なしESI-MS/MSと誘導体化反応を用いたα-pinene酸化体の官能基解析
α-Pinene (C10H16) are oxidized by ozone (O3), hydroxyl radicals, and NO3 radicals in the atmosphere. They can be converted to highly oxidized multifunctional organic compounds, which are significantly involved in secondary organic aerosol (SOA) formation. It is important for atmospheric chemistry to identify and quantify functional group of oxidation products of α-pinene. However, the structures of all oxidation products are still not understood. In this study, we investigated functional groups of the oxidation products of α-pinene by using an electrospray tandem mass spectrometry without liquid chromatography (no LC/ESI-MS/MS) and derivatization reactions. We will report relationship between functional groups of oxidation products and specific neutral loss. We will also report functional groups of the actual oxidation products of α-pinene identified using this relationship.
