OREAS C26d

OREAS C26d is a basalt blank chip certified reference material (CRM). The material was sourced from a quarry containing fresh olivine tholeiite (Newer Volcanics Province), near Melbourne (Victoria), Australia. OREAS C26d 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 C26d-DataPack.1.0.200605_123749.xlsx).
