Uni-chem Chemical Reagents Certificate Of Analysis Jun 2026
Elias blinked. "Wait. It's not the acid?"
The Certificate of Analysis (CoA) is a critical document that validates the quality, purity, and concentration of chemical reagents used in analytical and industrial laboratories. This paper examines the structure, content, and regulatory relevance of Uni-Chem’s CoA. It outlines the typical specifications—such as assay value, identity confirmation, impurity limits (heavy metals, residue on ignition), and physical properties—and explains their role in ensuring batch-to-batch consistency and compliance with pharmacopoeias (e.g., BP, USP) or ISO standards.

In the world of analytical chemistry, research, and industrial manufacturing, a reagent is only as reliable as its documentation. At , we don’t just sell chemicals; we provide verifiable certainty. The Uni-Chem Certificate of Analysis (COA) is the cornerstone of our quality promise.
The exact chemical name (e.g., Acetone, Methanol, Hydrochloric Acid) and its grade (e.g., AR Grade, HPLC Grade, ACS Grade).
Facilities operating under Good Laboratory Practice (GLP), Good Manufacturing Practice (GMP), or ISO certifications (such as ISO 9001 or ISO/IEC 17025) are legally required to maintain traceability. Auditors look at COAs to verify that the chemicals used in production or testing meet established standards. 3. Lot-to-Lot Traceability Elias blinked

This is the core data table of the COA. It lists the parameters tested, the acceptable limits (specifications), and the actual values recorded during testing for that specific lot. Test Parameter Specification Limit Actual Lot Result Analytical Method Used ≥is greater than or equal to Gas Chromatography (GC) Appearance Clear, colorless liquid Passes Test Visual Inspection Residue after Evaporation ≤is less than or equal to Gravimetric Water ( H2Ocap H sub 2 cap O ) Content ≤is less than or equal to Karl Fischer Titration Heavy Metals (as Pb) ≤is less than or equal to 5. Authorization and Sign-off
A Certificate of Analysis (COA) is an official document issued by a manufacturer’s quality assurance (QA) or quality control (QC) department. It confirms that a specific batch or lot of a chemical product meets its product specifications and quality requirements. This paper examines the structure, content, and regulatory
Measures particulate matter that does not dissolve in a specified solvent. Low values are crucial to prevent filtration clogging.
Uni-Chem's commitment to quality is likely reflected in adherence to international standards. Many chemical suppliers maintain certifications like for their quality management systems, which covers the rigorous control of manufacturing and testing processes. For pharmaceutical-grade materials, current Good Manufacturing Practices (cGMP) are the benchmark, often overseen by bodies like the US FDA. A CoA is the primary evidence that a product has been manufactured and tested in compliance with these stringent regulations.
