The Invisible Anchor of Laboratory Integrity: Understanding Uni-Chem Certificates of Analysis

• User’s responsibility: A CoA is batch-specific; always verify the lot number matches the bottle in use.
• Storage effects: CoA results are valid only under recommended storage conditions (e.g., cool, dry, away from light). Degradation after opening is not covered.
• Recommendation: Laboratories should maintain a CoA register and request fresh CoAs for critical applications like trace metal analysis.

In this article, we will dissect the Uni-Chem CoA, explain why it matters for compliance (ISO, GMP, USP), and teach you how to read every line to ensure your research stands on solid ground.

purity, composition, and physical properties.

A Certificate of Analysis (CoA) is a formal document issued by Uni-Chem’s quality control department that confirms a specific batch of a chemical reagent meets its advertised specifications. Unlike a Safety Data Sheet (SDS), which focuses on hazards and handling, the CoA focuses on
