) and the actual results of that specific batch. For example, while the specification might be 99.0%, the CoA will show if that exact lot tested at 99.4%. Alliance Chemical Impurity Profile Understanding the Uni-Chem Certificate of Analysis (CoA): A

  1. Centralized Repository: Create a shared drive (e.g., SharePoint or ELN) sorted by Batch Number.
  2. Incoming Inspection Form: Include a field for “CoA Verified (Y/N)” and “Batch Match (Y/N).”
  3. Expiry Tracking: Use the CoA’s retest date to trigger a calendar alert for disposal or re-testing.
  4. Supplier Audit: Request Uni-Chem’s ISO 17025 scope of accreditation to see what specific tests they are certified to perform.

Approval & Authentication

: Signed (digitally or physically) by an authorized quality control representative, often including an electronic approval statement. 2. Common Reagent Grades Provided Centralized Repository: Create a shared drive (e

  • Assay: Acid-base titration for bases, redox for oxidizers, or gravimetry.
  • Heavy metals: Thioacetamide method (limit: ≤0.001% as Pb).
  • Loss on drying: Heating at 105°C to constant weight.
  • Residue on ignition: 600°C muffle furnace.
