All ore grade gold OREAS® CRMs are tested by instrumental neutron activation analysis (INAA) on 0.09-1.0g aliquots (the sample size varies depending on the matrix) to confirm and quantify the absolute level of homogeneity. ORE Pty Ltd are the only manufacturers employing this stringent test and offer a guarantee of the homogeneity of gold (and PGE) in all OREAS® and custom CRMs irrespective of the presence of coarse gold in the source materials. ORE Pty Ltd’s latest innovation is the introduction of SuperCRMs® to the OREAS® range. OREAS SuperCRMs® feature certification of full ICP-OES and MS elemental suites by a range of digestion methods. Up to 179 analytes are characterised in a single CRM making them ideally suited as a control in ICP applications. With 105 SuperCRMs® available from a range of 236 OREAS® CRMs
