回顾了微波等离子体炬（MPT）作为一种新型激励源的发展历史。MPT作为AES的激发源的独特功能和缺点进行了概述。为了克服相对严重的基体效应，采用了去溶剂化、流动注射、在线预分离富集和在线标准加入等技术。一个氧护套Ar-MPT已被开发，以减轻由强氮相关的发射带所造成的干扰，这也被证明是有价值的，在降低噪声水平，以及提高激发能力。展望了未来可能的发展。
The development of an alternative excitation source, the microwave plasma torch (MPT) is historically reviewed. The unique features and shortcomings of the MPT as an excitation source for AES are outlined. To overcome the relatively severe matrix effects, desolvation, flow injection, on-line preseparation and preconcentration as well as on-line standard additions techniques have been adopted. An oxygen-sheathed Ar-MPT has been developed to alleviate the interferences caused by the strong nitrogen-related emission bands and this has also been shown to be valuable in reducing noise levels as well as improving the excitation capability. Some possible future developments are envisioned.
