[SMP38-P09] Tandem LA – LIBS Analysis for Determination of P, F, Ca, Na, Cl and Trace-level REE in Apatite.
Keywords:LA-ICPMS, LIBS, REE
While LA-ICP-MS has been used to detect and measure trace level REE’s and transition metals in apatite minerals, the precise determination of phosphorus and halogen elements in apatite and other minerals has proven difficult by traditional methods of scanning electron microscopy (SEM-EDS) and laser ablation ICP-MS (LA-ICP-MS). In this study, we present Tandem LA – LIBS analysis that combines both Laser Induced Breakdown Spectroscopy (LIBS) and LA-ICP-MS for detection and measurement of P, F, Ca, Na, Cl in apatite minerals as well as REE’s and transition metals. The Tandem LA – LIBS technique is an emerging in-situ analytical technique in geoscience to fully characterize the chemistry of halogen and hydrous minerals.
