A mass spectrometer matched with ICP as the ion source. The sample was prepared by the two methods of melting lithium ferrite and difluorohydrogen potassium to solve the decomposition of the refractory sample. The ruthenium, osmium and indium were used as internal standards respectively, and the flux was matched in the standard series to solve the influence of the matrix effect, and 34 trace elements were directly determined without separation and enrichment.
