X-Ray Fluorescence (XRF) Applications

X-Ray Fluorescence (XRF) is a wide ranging technique, allowing analysis of elements from Na to U with concentrations from high % to low ppm with high accuracy and reproducibility. Typical materials for XRF analysis are silicate minerals. The equipment has the capability to analyse solids, fused beads, and powders, and has an automated sample changer to allow fast throughput of samples. A four sample fusion furnace is available to ensure rapid, reproducible and easy fusion of most materials ready for analysis.
