The TIMS, SIMS, and SHRIMP are common techniques used for dating isotopic REE deposits. In this work, LIBS methodology was employed using three different configurations: standard LIBS, LIBS with an applied magnetic field, and LIBS with both an applied magnetic field and target sample heating within an optimal temperature range. ICP-MS, ICP-MS/MS, ICP-TOF-MS, HR-ICP-MS, MH-ICP-MS, and MC-ICP-MS are popular techniques for REE analysis thanks to their ultrahigh sensitivity, minimal interference effects. Direct measurement of trace rare earth elements (REEs) in high-purity REE oxide using the Agilent 8800 Triple Quadrupole ICP-MS with MS/MS mode Introduction Rare earth elements (REE) are widely used in advanced technology. Praseodymium (Pr), neodymium (Nd), samarium (Sm) and dysprosium (Dy) are. Rare earth elements (REE) are crucial elements that offer unique properties that are crucial in much of today's technology like EVs, turbines, computers etc. REE consist of the entire row on lanthanides along with scandium (Sc) and yttrium (Y). Rare earth elements are not found in concentrated ore. Within this paper, we investigate the potential of combining passive reflectance (imaging and point sampling) with laser stimulated luminescence (point sampling) spectroscopic measurements across the visible, near and shortwave infrared for REE detection in non-invasive near-field mineral. This article highlights spectroscopic analysis in rare earth detection, focusing on its speed, sensitivity, and multi-element capabilities. It showcases key techniques and industrial applications, underscoring their role in advancing the rare earth industry's digital transformation.
