A Certificate of Analysis (COA) for chemical reagents needs to be precise and professional to ensure laboratory compliance and safety.
Problem 3: The Portal Requires a “COA Access Code”
To comply with the new UPD mandate, follow this exact workflow. Do not rely on a printed copy included in the shipping box; that is likely a reference copy only.
What a Certificate of Analysis (CoA) Is
- Verify Dates: Always cross-reference the "Issue Date" on the CoA with the date of receipt.
- Check Version Numbers: Look for revision numbers (e.g., Rev 01, Rev 02) on the document to ensure you hold the current version.
- Consult Technical Support: If an "Updated" CoA shows a significant deviation in purity from the original specification, contact Unichem technical support immediately to assess impact on experimental results.
