4. Conclusion
A new analytical method for REE determination was stablished using
ICPMS with Ar-O2 mixed plasma to aid the formation of MO ions. The
combination of standard mode and the modification with O2 allowed
the accurate determination of REE in minerals after acid treatment.
The validity of this method was assessed through CRM analysis and
through the analysis of real-world samples. The REE concentrations
evaluated and normalized to chondrite REE levels allowed the analysis
of basaltic rocks study in terms of their origin.
