Abstract: A method was developed for direct determination of Tm,As and Si in high purity europium by ICP-MS /MS. The interferences on the analysis were efficiently removed by using H2 and O2 reaction cell gas in MS / MS mode. Under the optimized conditions,the background equivalent concentration of 0. 0005763,0. 08435 and 8. 268 μg·L- 1 was achieved for Tm,As and Si,respectively. The spike recoveries of these three elements were 98. 71% 103. 26%,and the RSDs was 0. 22% 3. 75%. The method was suitable for the direct determination of impurities in high purity europium of 99. 999% or above.
