Chrysos PhotonAssay, the company’s flagship product, is a quantitative, chemistry-free replacement for Fire Assay on-site and in the laboratory. Hitting samples with high-energy X-rays, Chrysos PhotonAssay causes excitation of atomic nuclei allowing enhanced analysis of gold, silver and complementary elements.
