| 摘 要： | 本文介绍了一种新型延长炬管的设计。该炬管使在电感耦合等离子体原子发射光谱仪(ICP-AES）上同时测定氮及其它金属元素成为可能，并且在不同程度上改善了一些金属元素的检测限。本文利用该炬管．在ARL 3520光谱仪上同时测定了生物标准样品中的氮及Fe，Mn、Cu、Zn等四种金属元素。结果与定值吻合，相对标准偏差均小于5%。

| Abstract: | This paper describes a new design of the extended torch with which it is posSible to determine nitrogen and beveral metal elements simultaneously by ICP-AES. The detection limits of these metal elements aft improved to different extent. The proposed method has been applied to the determination of N, Fe, Cu and Zn in 4 Standard biological reterence materials. The results obtained were in good agreement with the certified vaines. |
