XU Qing-fu, ZHOU Chang-xiang, ZHANG Wen-juan (Shandong Institute and Laboratory of Geological Sciences, Shandong, Jinan 250013, China)
Trace germanium in geochemical samples determined by off and on-flow samples supply AFS, the lower limit of determination is 0.04×10 -6,linear scope is 0～500μg/L, precision is 1.6%, and extraction ratio of standard substance in samples is 98.1%～103.5%. This method is demonstrated accurate and reliable through testing of standard samples.
