采用选择性离子流管质谱法(SIFT‐MS)和质子转移反应质谱法(PTR‐MS)研究了六甲基二硅氧烷低温高压等离子体中的离子分子反应。这些技术为在这样的等离子体环境中可能发生的反应提供了新的线索,并验证了许多先前基于等离子体相质谱的反应途径。然而,SIFT - MS和PTR - MS的结果引起了人们对h30 +离子在启动低聚离子形成方面的可能重要性的关注,这一点在等离子体-质谱研究中被忽视了。
Selected ion flow tube mass spectrometry (SIFT‐MS) and proton transfer reaction mass spectrometry (PTR‐MS) are used to explore ion‐molecule reactions in low temperature and pressure plasmas of hexamethyldisiloxane. These techniques shed new light on possible reactions taking place within such plasma environments and validate many of the reaction pathways previously advocated based upon plasma‐phase MS. However, SIFT‐MS and PTR‐MS results draw attention to the possible importance of the H3O+ion in initiating the formation of oligomeric ions, a point previously missed in plasma‐MS studies.
