Conversion of rare earth elements to molecular oxide ions in a dynamic reaction cell and consequences on their determination by inductively coupled plasma mass spectrometry
The behaviour of rare earth elements (REEs) ions within a dynamic reaction cell (DRC) pressurized with oxygen was investigated, in order to explore their determination at m/z +16 by inductively coupled plasma mass spectrometry (ICP-MS). Under the optimized conditions, the conversion of REEs to molec...

The behaviour of rare earth elements (REEs) ions within a dynamic reaction cell (DRC) pressurized with oxygen was investigated, in order to explore their determination at m/z +16 by inductively coupled plasma mass spectrometry (ICP-MS). Under the optimized conditions, the conversion of REEs to molecular monoxide ions was nearly quantitative (>96%), with the exception of Tm (78%), Eu (11%) and Yb (6%). Moreover, the formation of dioxide ions was generally lower than 1%. According to these results, a new method for the determination of REEs in digests from geological samples was developed. After microwave-assisted acid digestion, the solutions were directly analyzed by ICP-MS, determining REEs at m/z +16. The interferences due to dioxide and un-reacted ions were carefully evaluated by taking into account the actual concentration of REEs in sediment samples.
