【摘要】 <正> 流动注射分析(FIA)作为一种灵活高效的试样一试剂溶液处理手段与原子吸收光谱分析联用显著地扩展了后者的应用前景。氢化物发生-原子吸收流动注射分析(HGAAS-FIA)作为这类联用技术以其显著的特点引起了人们的注意。本文拟将数年来的文献和作者的实践作一概述。实验装置及分析技术氢化物发生-原子吸收流动注射分析的工作原理是:将一定体积的试样溶液(数十至数百微升)注入到连续流动的载流(去离更多还原

【Abstract】 Developments in the application of flow injection techniques to hydride generation atomic absorption spectrometry(HGAAS) were reviewed. The benefits of flow injection hydride generation systems over conventional methods were summerized. Mechanisims for the greater tolerance of interferences in FIA-HGAAS systems were discussed.更多还原
