OREAS C26e
SKU: C26e
OREAS C26e is a basalt blank chip certified reference material (CRM) with a
nominal particle size of minus 8mm to simulate RC drill chip samples. The
material was sourced from a quarry containing fresh olivine tholeiite (Newer
Volcanics Province), near Melbourne (Victoria), Australia. OREAS C26e contains
55 certified values including full ICP-OES and MS elemental suites by 4-acid
digestion and Au by fire assay. Indicative values for 86 additional elements are
also available. OREAS C26e is available in 500g bags, 20kg plastic buckets and
200kg drums.
