本文对等离子体当作质谱测定法用的大气压等离子源进行了简要的评论,讨论了微波感应等离子体(MIP)的特性和分析能力,给出了近期研制的带有钽注入器探针的微波感应等离子体源(MIP—TIP)的结构。现在的结构对离子信号的灵敏度和稳定度作了改进并提高了发生器到谐振腔的功率转换效率,讨论了使用这种改进等离子体源获得的初步信息。
In this paper, a brief review of the plasma as an atmospheric pressure plasma source for mass spectrometry was discussed. The characteristics and analytical capabilities of microwave induced plasma (MIP) were discussed. The recent development of microwaves with tantalum injector probes Inductive plasma source (MIP-TIP) structure. The current structure improves the sensitivity and stability of the ion signal and increases the power conversion efficiency from the generator to the resonator. The preliminary information obtained using this improved plasma source is discussed.
