QCRM-2-138 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 Manganese Alloy and as a calibration standard for the calibration of equipment used for analyzing similar materials.
This document has been updated to a COA, as more data became available, enabling the certification of some analytes.
