High pressure tax produced by Tianjin Yitong electronic factory and ICP-MS laboratory in China University of Geosciences Beijing was also utilized. Based on a va- riety of experiments about sample dissolution, dilution multiples and instrument detection conditions, the method of sulfide (100 mg) with aqua regia of acid solution in high pressure tax and the method of ICP-MS detection under 2000 times dilution were established. The results demonstrated that detections of standards coincided well with the given values and the relative standard deviations (RSD) were below 5%. In this study, the values of rare earth elements, lithophile elements, high field strength elements and Au, Ag in sulfides such as pyrite could be analyzed in single ex- periment process.
