OREAS C27e

OREAS C27e 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 10mm to simulate RC drill chip samples.

In addition to the 500g and 1kg pack sizes (see list under ‘Add to cart’), 20kg and 200kg drums are available upon request for AUD$420 and AUD$3140 respectively (please contact sales@ore.com.au).

OREAS C27e contains 60 certified values by full ICP-OES/MS suite by 4-acid digestion and Au by fire assay. Indicative values for 70 additional elements are also available. Tabulated round robin laboratory results of all elements together with analytical method codes, uncorrected means, medians, standard deviations, relative standard deviations and per cent deviation of lab means from the corrected mean of means (PDM3) are presented in the detailed certification data for this CRM (OREAS C27e-DataPack.1.0.200605_124215.xlsx).
