Demination of As content in neodymium chloride industrial raw materials by ICP-MS,found that exist matrix interference,so we take a test value by internal standard calibration.sample result by XRF scan is ND,Using ICP test although exist certain spectrum interference,but the test result compare with ICPMS is two orders of magnitude difference,By looking for some literature found that Nd have an isotope150,The in terferenceof double charge is inherent in ICP-MS,Although can through the selection of appropriate instrument operating conditions to reduce the interference,But it can not fundamentally eliminate,Finally using the model reaction,AsO instead of As to avoid the interference of double charge to get the correct test results.
