Vaporization Behaviors of Analytes Introduced by Electrothermal Vaporization in Inductively Coupled Plasma-Atomic Emission Spectrometry

本文考察了电热蒸发进样 ETV/ICP-AES 技术中蒸发电流对不同挥发性元素的信号强度及峰形的影响;探索了蒸发器体积及其结构对分析物蒸发行为和信号的影响;本文还探索了平台技术在 ETV-ICP-AES 中的应用。并相应得出了一些有益的结论。

The vaporization behaviors of analytes with different volatilities in electrother- mal vaporization(ETV)/inductively coupled plasma(ICP)-atomic emission spectrometry (AES)were studied.These include the effects of vaporizing current,volume and geometry of the vaporizer.The application of platform technique in ETV-ICP-AES was also explored.
