M1 MISTRAL, Compact Tabletop µ-XRF Spectrometer

Analyzing Jewelry

Micro-X-ray fluorescence with the M1 MISTRAL is a very good option for the analysis of jewelry samples: Non-destructivity leaves the sample unharmed, simultaneous detection of all elements allows a complete characterization of the material and the small spot size permits the analysis of irregular and inhomogeneous samples.

The achieved accuracy is not quite as high as with fire assay, but it is more than sufficient for quality control of jewelry manufacturing, screening of unknown samples and detection of traces down to the ppm-range.
