Certified Reference Materials
As part of our promotion of quality and good practise in the refining and trade of gold and silver, LBMA produces and sells Certified Reference Materials (CRMs).
CRMs are available to any laboratories that want to calibrate their analytical equipment using LBMA standards. CRMs are an essential component of GDL best practise; helping to ensure that existing GDL refineries maintain current LBMA standards and listing and for prospective GDL refineries they provide a benchmark of the standards required.
The silver CRMs are sold as sets of two units (one of AgRM4 and one of AgRM5), with each unit being approximately 21x21x6 mm and weighing approximately 28 g.
The Certificate of Analysis provides the element concentrations as well as details of the manufacturing process, homogeneity testing and other important information. The Certificate of Analysis can be found here.
The price (excluding shipping costs) for a set of two units is:
- Good Delivery List Refiners and LBMA Members: US$4,275
- Other purchasers: US$4,700
An invoice will be raised in respect of the specific order value. Orders will be despatched after receipt of payment. Delivery should be complete within 30 days of the despatch authorisation.
New gold CRMs are available for purchase now with delivery from February 2021.
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!
