A Quick Assay for Gold?
Chrysos Corporation is commercialising the PhotonAssay technology, originally developed by the CSIRO. Based on the principles of photon activation analysis, the method uses a high-energy X-ray source to excite nuclear changes in any gold atoms present in a sample, and then measures a characteristic signature emitted by these atoms.
The process is non-destructive, rapid, highly specific and capable of providing a true-bulk analysis of samples, weighing 0.5kg or more.
