摘要:

Germanium in 13 USGS standard silicate rooks was determined by flameless atomic absoprtion using a procedure which permits the determination of 0.2 ppm of germanium in as little as 50 mg of sample. The mean germanium content found is (in ppm Ge) for the new USGS standards: BHVO‐1, 1.60; SDC, 1. 51; STM‐1, 1. 32; QLO‐1, 1. 28; RGM‐1, 1. 24; and for‐ the older USGS standards: W‐l, 1.S3; BCR‐1, 1.39; G‐l, 1.19; GSP‐1, 1.16; AGV‐1, 1.06; G‐2, 0.96; PCC
