QCRM-3-044 is a certified reference material that is matrix matched. It 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 nickel ore analysis and as a calibration standard for the calibration of equipment used for analyzing similar grade materials.
