摘 要：This paper reported the mass spectrum interfering problems during analytical procedures with trace rare earth elements(REES) as impurities in fifteen high purity rare earth products using ELAN 9000 inductively coupled plasma mass spectrometry(ICP-MS) *** interfering effects caused by interfering species originated from background mass spectrum,isobaric overlaps,mass spectrum overlaps and matrix-induced polyatomic ions that interfer the quantification of the specified analytes were evaluated deeply. The relationship between polyatomic ions originated from matrix-induced and the instrumental conditions was also *** quantitative analysis,the appearance concentrations of polyatomic ions arose from matrix-induced and matrix mass spectrum overlaps were *** to the mass spectrum interferences,the resolving methods of correction interferences were put *** limit of quanlitation (LOQ) for trace of REEs impurities and acquiring purity under direct determination of fifteen high purity rare earth products were also investigated.
