摘　　要：本文研究将自动流动注射分析体系用于氢化物发生——原子吸收光谱法测定化妆品样品中μg/L 水平的砷。分析速度可达160样/h,测定20.0μg/L 砷的相对标准偏差为1.0%(n=11),在样品消耗为400μl 时方法的检出限为0.3μg/L。添加砷测定回收率为98.5～101.4%。A flowing injection analysis(FIA)system with automated sample introduction was used for the determination of trace arsenic in cosmetic sample by hydride generation atomic absrption spectrom- etry(HGAAS).The detection limit was 0.3μg/L and relative stan- dard deviation 1.0%(n=11)at a level at 20.0μg/L(As).The sampling frequency was 160/h while sample consumption was 400μ1,per injection.
