We utilise the leading technology available to assay and confirm the precious metal content of articles presented for testing. We work with our customers to process the vast majority of assaying through non-destructive techniques.
For hallmarking requirements in particular, we select samples from every batch of work received and analyse utilising X-ray Fluorescence Spectrometry (XRF) machines.
We also test utilising more traditional methods such as cupellation (gold) and potentiometric titration (silver).
As well as detection of hazardous elements, we can also provide Melt & Assay – melting and confirmation of content of scrap precious metal – through the following methods:
CUPELLATION (ISO 11426 / Accredited UKAS 17025)
POTENTIOMETRIC ANALYSIS OF SILVER
