摘要
本文叙述了国产半米平面光栅光程短、光强好、谱线锐度佳的特点,通过最佳条件选择,改进分析方法,使其测金灵敏度为3×10^(-9)g,取样10g可测定含金量范围为0.3—1000ppb,取得了很好的效果。
This paper describes the characteristics of domestic half-meter plane grating such as short optical range, good optical intensity and excellent sharpness of spectrum. The anaiytical methods have been improved through the selection of optimum condition so that the sensitivity for gold analysis becomes 3×10_(-9)g and the range of 0.3—1000ppb gold concentration can be determined using 10g sample, the very good result has been obtained.
