Assaying

As a leader in the precious metal world, Argor-Heraeus relies on highly skilled laboratory technicians, state-of-the-art technology and the vital expertise of our Swiss Governement Sworn Assayer. This ensure high precision in precious metal assaying.

Tradition meets technology

Rooted in a tradition that spans over 4,500 years, our assaying practices combine time honored techniques with cutting edge technology. As an LBMA approved referee laboratory since 2003, we uphold the legacy of fire assaying, still the most accurate method for gold analysis, while also employing a suite of advanced analytical tools. From potentiometric titrations for silver to ICP OES for complex matrices, our laboratory is equipped to handle the full spectrum of precious metal testing with unmatched precision.

Our laboratory

Our ISO/IEC 17025 certified laboratory, officially recognized by the Swiss Central Office for Precious Metals Control, is staffed by expert assayers who tailor each analysis to the specific characteristics of the sample. Whether verifying the fineness of a gold bar or detecting trace elements in an alloy, we apply the most effective methods to deliver results our clients can trust. At Argor Heraeus, assaying reflects a seamless blend of tradition and innovation, ensuring integrity at every step of the value chain.
