REEs in the Field

• The world’s dependency on critical rare earth elements (REEs) has never been higher. However, the ability to properly analyze these elements in the field has been underwhelming. Conventional portable XRF, with maximum X-ray tube voltages of 50kV, can measure the light REEs but struggle to measure heavy REEs in any practical way due to inadequate excitation and severe spectral overlaps with common metals such as Fe, Cu, Ni.

PowerHouse is the answer

• Utilizing an 80kV miniature X-ray tube, the PowerHouse can efficiently excite the K shell emission lines for both light and heavy REEs. By analyzing these high energy K-lines, the complicated spectral overlaps with common metals are avoided completely, yielding unprecedented limits of detection and better performance than any other portable XRF.

X-Ray Fluorescence (XRF) Spectrometry is a non-destructive elemental analysis technique that identifies and quantifies elements in materials by analyzing the characteristic X-rays emitted when a sample is bombarded with high-energy primary X-rays. This process excites atoms, ejecting inner electrons, and as outer electrons fall to fill the void, they release unique fluorescent X-rays, acting like an elemental fingerprint, allowing for rapid, precise, and often minimal-prep analysis of solids, liquids, and powders.
