With the Certified Reference Material (CRM) or Reference Material grade comes the Certificate of Analysis (CoA). Within the CoA, there are several quality parameters which are critical to understand: accuracy, consistency, homogeneity, purity, and stability. Also, what is being certified is important to understand – namely, the certified
