OREAS C27h
SKU: C27h
OREAS C27h 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. It
contains certified values for Au by fire assay and full ICP-OES and MS
elemetnal suites by 4-acid digestion. Indicative values for additional
elements are also available.
OREAS C27h is available online in 500g bags, 20kg plastic buckets or
200kg drums.
