英文摘要	<正>1引言原子荧光光谱法(AfS)是一种选择性好、检测能力优异的痕量/超痕量元素分析方法,其仪器结构简单、易于维护,在各行业均具有非常广泛的应用基础。因而,研发新型AfS系统,改善仪器检测性能,无疑具有重大的实用意义。增加激发光源强度是提高AfS仪器灵敏度的有效途径之一。文献[1~4]将ICP-AfS/IfS仪器的空心阴极灯(HCl)光源供电方式改变为安培级大电流微秒脉冲供电(HCMP),并成功改善了仪器对Cu,Ag,zn,Al,CA,Eu,yb等元素的检出限。; A high sensitive hydride generation( HG) atomic fluorescence spectrometric system was developed using high current microsecond pulsed hollow cathode lamp( HCMP-HCL) as the excitation source and its performance was evaluated.Test results confirmed that the excitation source could give out intensive atomic spectral lines.System precision( RSD,n = 7) was 1.1% for arsenic and 1.4% for selenium.Detection limits( DLs,3) were 0.0066 μg / L and 0.0075 μg / L,respectively.The developed AFS system was proved to have high reliability,low detection limit and remarkable improvement of analysis capability compared with that of commercial AFS instruments.; 国家重大科学仪器设备开发专项项目(No.2011YQ140149)资助
