摘要
Spark-source mass spectrometry for quantitative analysis of Apollo-17 lunar rock(70017-291) is described. About 5rag powder lunar rock sample, without any eanduetive material mixed in it, was pressed on the surface of T type electrode. A single exposure was made under the optimum condition After development,the relative sensitivity, coefficients are calculated on the basis of the single exposure by U.S. Geological Survey Standard Rock AGV-1. More than 20 elements be be determined by this technique with a typical precision of ± 20%.
