气相色谱和原子吸收分光光度法的结合为挥发性有机金属物质分析提供了高灵敏度和专一性的方法,并且已应用于空气、水、沉积物和生物组织环境样品中As、Pb、Se和Sn的烷基衍生物分析。本文讨论了在可达到的灵敏度条件下样品的导入技术以及检测器的设计。环境中的许多具有挥发性的有机金属化合物可以用气液色谱(GC)法分离。不过,它们的浓度很低,即使在最适宜的条件下,由于被分析物中浓度高得多的碳氢化合物的存在,而掩盖了有机金属化合物所产生的信号,因此不 The combination of gas chromatography and atomic absorption spectrometry provides a highly sensitive and specific method for the analysis of volatile organometallic species and has been applied to the determination of As, Pb, Se and B in environmental samples of air, water, sediments and biological tissues Analysis of alkyl derivatives of Sn. This article discusses sample introduction techniques and detector design at achievable sensitivity. Many of the volatile organometallics in the environment can be separated by gas liquid chromatography (GC). However, their concentration is so low that even under the most suitable conditions, the signal generated by organometallic compounds is not masked due to the presence of much higher concentrations of hydrocarbons in the analyte
