CCD-Ⅰ型平面光栅电弧直读发射光谱仪测Ag、B、Sn、Pb、Mo

Detection of Ag, B, Sn, Pb and Mo by Plane Grating Arc Direct Reading Emission Spectrometer CCD-1

采用垂直电极直接燃烧法,以交流电弧为激发光源,在改造完成的摄谱仪上进行摄谱,采用国家一级标准物质硅酸盐系列GSESⅠ为标准,河北廊坊物化探研究所配制的固体缓冲剂,以Ge为内标,电弧发射光谱法测定地球化学样品中的Ag、B、Sn,Pb、Mo对谱图进行分析。利用这种方法有效的抑制了基体元素的干扰,极大的改善了测定方法的准确度和精密度,降低了元素的检出限。

This study uses the plane grating arc direct reading emission spectrometer CCD-1 for detecting Ag, B, Sn, Pb, Mo for geochemical samples, using national level standard material GSES Ⅰ as standard. The method suppresses the interference of the matrix elements, improves accuracy and precision of determination method and reduces the detection limit of the elements.
