Good Delivery

Reference Materials

To promote quality and good practice in the refining and trade of gold and silver, we produce and sell Certified Reference Materials (CRMs).

CRMs are available to any laboratories wishing to calibrate their analytical equipment to LBMA standards. CRMs are an essential component of Good Delivery best practice and help to ensure that existing refineries on the Good Delivery List (GDL) maintain current LBMA standards and listing. For prospective GDL refineries CRMs provide a benchmark of the standards required.

Gold CRMs

The LBMA Reference Material Steering Committee has produced the latest set of high purity gold certified materials suitable for the validation of analytical methods as well as for calibration of analytical instruments to the LBMA Good Delivery standard.

These materials represent an evolution of the earlier reference materials AuRM1 and AuRM2 which proved to be immensely popular amongst quality laboratories around the world. The elemental concentrations have been based on feedback received from users of the previous materials. Now with added cadmium - and cobalt, indium, iridium, and ruthenium.
