This reference material is produced and certified by BAM (Bundesanstalt für Materialforschung und -prüfung) in cooperation with the WG Precious Metals of the Committee of Chemists of GDMB. It is an officially recognized European Reference Material (ERM®) designed for precision calibration of XRF analyzers, including handheld and benchtop instruments.

Features

• Certified by BAM under ISO/IEC Guide 98-3:2008 with traceability to the SI (International System of Units).
• Intended for X-ray fluorescence spectrometry (XRF) calibration and quality control.
• Specifically developed for calibration of handheld XRF analyzers used in precious metals testing.
• Supplied in round slices (15.8 mm diameter, 0.25–0.3 mm thick) embedded in acrylic glass discs (40 mm diameter, 5 mm thick) for stability and ease of handling.
• Certified values derived from multiple laboratories using methods including fire assay and ICP-OES.

Instructions for Use

• Ready to use without sample pre-treatment.
• Avoid touching the sample surface; if needed, clean gently with pure ethanol.
• Store in a dry, clean environment at ambient conditions.

Applications

• Calibration and verification of handheld XRF analyzers for 18K gold jewelry, refining, and precious metals recycling.
• Routine quality control checks in analytical laboratories.
• Training and demonstration in academic or testing facilities.
