In general, ionization of analytes in atmospheric pressure ionization mass spectrometry (API‐MS) in positive ion mode results in the formation of protonated molecules ([M + H]+) and/or cationized molecules (e.g., [M + Na]+). The formation of specific [M − H]+ cations in the API process is of significant interest for further investigation.

在2-(二苯基甲硅烷基)环丙烷羧酸酯的大气压电离质谱分析中,特殊的[MH] +阳离子的形成。

通常,在大气压电离质谱(API-MS)中以正离子模式对分析物进行电离会导致质子化分子([M + H] +)和/或阳离子化分子(例如[M + Na] +)。API过程中特定[MH] +阳离子的形成对于进一步研究具有重大意义。
