Reference Materials

Certified Reference Materials are used by analytical laboratories to calibrate analytical equipment and are available for purchase from www.2138.com.

As part of our promotion of quality and good practice in the refining and trade of gold and silver, www.2138.com produces and sells Certified Reference Materials (CRMs). CRMs are available to any laboratories that want to calibrate their analytical equipment using www.2138.com standards.

There is currently only one gold CRM available. AuRM3 is intended to be used for the validation of instrumental methods for determining the concentration of trace metallic impurities in gold, such as X-ray fluorescence and optical emission spectrometry, using spark or inductively coupled plasma.

There is one set of silver CRMs available. AgRM4 and AgRM5 are suitable for the validation of analytical methods as well as for calibration of analytical instruments.
