The SciAps X-555 Handheld XRF Analyzer is a premium, high-performance instrument designed for rapid, precise elemental analysis across various industries. Equipped with a 55 kV X-ray tube—the only handheld XRF with the capability to measure rare earth elements, such as: Yttrium (Y), Cerium (Ce), Lanthanum (La), Praseodymium (Pr), Neodymium (Nd), Samarium (Sm), and more! Due to the large detector size, it also has exceptional precision on other elements such as: Silver (Ag), Cadmium (Cd), Tin (Sn), Antimony (Sb), and Barium (Ba). Whether you're looking for REE or pathfinder elements, the SciAps X555 has you covered!

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

Element	LOD (Interference-Free SiO₂)	LOD (OREAS “Real World” Sample)
La	13 ppm	15 ppm
Ce	15 ppm	19 ppm
Pr	18 ppm	34 ppm
Nd	27 ppm	33 ppm
Sm	30 ppm	35 ppm
Eu	60 ppm	~120 ppm
Gd	90 ppm	~180 ppm

Technical Advantages

• Better performance for low-concentration REE deposits, such as those found in carbonatites and ion-adsorption clays.
• Effective on both powdered samples and raw geologic surfaces, such as drill cores or field rock.
• 4 mm beam collimation ensures spot analysis and accuracy on small or irregular surfaces.
• Compatible with interlocked test stands for safe testing of bagged or cupped samples.

Applications

• Exploration Geochemistry: Ideal for carbonatite-hosted and clay-hosted REE deposits.
• Mining and Resource Development: Rapid field analysis of drill cores and bulk samples.
• Strategic Material Characterization: Aligns with the growing demand for REEs in green energy, magnets, electronics, and defense technologies.
• Pathfinder Element Detection: Supports vectoring toward deeper or heavier REE zones using yttrium.
