In the analytical chemistry field, certified reference materials are used as standards that are inserted as blind samples within a batch of samples during analysis. The purpose could be for validating analytical measurement methods as well as to calibrate analytical instruments etc. 

These standards at Qotho are referred to as “Qotho Certified Reference Materials” abbreviated as QCRM’s. 

The benefits of using these standards are critical to support decision-making around mineral resource production/management, commodity valuation in marketing and compliance with environmental regulations.
