The Evident Scientific Vanta Max 55 kV handheld XRF analyzer is a high-performance field instrument designed for rare earth element (REE) mining, exploration, and geochemical analysis. Built for rugged field use yet capable of laboratory-grade precision, the Vanta Max delivers fast, repeatable elemental data from magnesium through uranium—including enhanced sensitivity for light and mid-range rare earths such as La, Ce, Pr, Nd, Sm, Eu, and Gd.

With its 55 kV excitation energy, the Vanta Max achieves greater photon flux for heavy elements, improving REE signal response, peak separation, and detection accuracy even in complex carbonate or silicate matrices. This makes it one of the most capable handheld analyzers available for rare earth exploration, carbonatite mapping, and REE-bearing mineral identification.

Evident’s Axon Technology™ pulse processing and large-area SDD detector deliver industry-leading count rates, low background noise, and excellent light-element sensitivity—all while maintaining high stability in challenging field environments.

Mining and exploration professionals frequently deploy new handheld XRF analyzers for real-time elemental analysis in the field.
