The Sheffield Assay Office has over 240 years of experience in the testing, analysis and hallmarking of precious metal items. Our Analytical Services, with over 32 years of UKAS accreditation (0012), uses this longstanding expertise to provide the foundation for accurate precious metals analysis. Skillfully combining traditional methods with modern instrumentation and techniques, we provide a reliable melt and assay service.
Precious metals analysis is of paramount importance to manufacturers, for the control of quality at every stage; from raw material through work-in-progress, to life-expired articles or scrap.
Mixed parcels of scrap being traded are difficult to evaluate and consequently carry an element of risk to both parties.
Sheffield Analytical Services' melt & assay service addresses this problem, through production of a stamped homogeneous and assayed bar from the mixed precious metal parcel.
The accompanying certificate gives the bar a unique identity by recording its precise content and weight, thus permitting subsequent sale or purchase with peace of mind.
