摘要
直读光谱分析不锈钢中氮含量 ,确定了氮的光谱分析线、最佳分析条件 ,分析样品的制备要求 ,共存元素的影响和氮校准曲线的拟合情况。本法具有良好的准确度和精密度 ,氮元素的分析检出限为6 .3μg/ g,检测范围为 0 .0 0 1%— 0 .4 2 %。
The method for the determination of nitrogen in stainless steel by direct readin g spectrometry was developed.The analysis line of nitrogen and the operation con dition were optimized.The preparation method of sample element interference and the standard curve fitting of nitrogen were studied. The method is precise and a ccurate with the detection limit of 6.3μg/g,and the detection range of 0.001%— 0.42%.
