SciAps X-555 Rare Earth Element (REE) Analysis Capabilities

• First handheld XRF with a 55 kV X-ray tube, exceeding the industry-standard 50 kV.
• 55 kV enables stronger excitation of REE lines—especially for light REEs—and delivers dramatically improved detection limits.
• Equipped with a large 50 mm² Silicon Drift Detector (SDD), maximizing count rates for better signal quality and faster measurements.
• Achieves 10x higher count rate for La and up to 30x for Sm, compared to typical 50 kV analyzers.

Light REEs (LREEs)

• La (Lanthanum)
• Ce (Cerium)
• Pr (Praseodymium)
• Nd (Neodymium)
• Sm (Samarium)

Heavy REEs (HREEs)

• Eu (Europium)
• Gd (Gadolinium)
• Y (Yttrium) – Also acts as a pathfinder for heavier REEs such as Dy, Tm, and Yb.

SciAps X-555 Limits of Detection (LOD) for REE

Technical Advantages
