OREAS C27f

OREAS C27f is a rhyodacite blank chip certified reference material (CRM). The material was sourced from a rhyodacitic unit of the Mt Dandenong Igneous Complex located approximately 34km east of Melbourne (Victoria), Australia. The CRM has a nominal particle size of minus 8mm to simulate RC drill chip samples. OREAS C27f contains certified values for Au by fire assay and full ICP-OES/MS elemetnal suites by 4-acid digestion. Indicative values for additional elements are also available.

OREAS C27f is available online in 500g bags, 20kg plastic buckets or 200kg drums.
