Abstract

Abstract

The analytical method of major, trace and ultra-trace elements is applied to geological samples using ICP-MS. In order to minimize matrix effects of inter-elements, the matrix-matched calibration solutions were prepared, simulating the composition of natural rocksobtained from statistically-calculated average values of 20 geological samples. The resulting values are then normalized. Two separate internal standards of 115 In-103Rh are selected to compensate the drift of analytical signals. Polyatomic ion interference is calibrated by measuring the oxides(MO⁺)and hydroxides(MOH⁺)with individual element solution for the ratio of MO⁺/M⁺ and MOH⁺/M⁺ and the concentrations are then equivalently calculated. The proposed method is applied to the analysis of seven standard reference materials. For the most trace elements, the relative errors between this work and the recommend values are greater than 10% and the relative standard deviations are greater than 5%.
