QCRM-5-069 is a certified reference material which is suitable for use as random control samples in routine analytical laboratory quality control, when inserted within a batch of samples and measured in parallel to the unknown. The QCRM can also be used as a control sample in the analysis of samples of a similar type, verification of analytical methods for Copper Concentrate and as a calibration standard for the calibration of equipment used for analysing similar materials.
This document was updated, as more data became available for As, Bi, Mo and Se. Only the data for these for analytes were received during this update, with two of the analytes becoming certifiable.
