How to check a peptide certificate of analysis
A certificate of analysis (COA) belongs to an identified material and batch. Start with the lot on the container you receive, then check the document against that lot. A certificate for another batch does not establish the results for yours.
Start with the label, not the headline percentage
Put the container, order confirmation and certificate beside one another. Record the material name, catalogue code, pack size and lot number. If one document uses an abbreviation while another uses a full chemical name, ask the supplier to confirm the relationship in writing. Do not silently substitute a similar name.
For an Aminovera order, use batch lookup and the documentation page to find the published status. A pending document is not an available certificate. If a required record is missing, ask for it before releasing the material into your workflow.
Read each result in context
A specification states an acceptance criterion. A result reports what was observed. Record both, with the units and method reference. A number without a method or acceptance criterion is harder to assess; it should not become a blanket assurance of quality.
Use this receipt record:
| Field | What to record | When to ask for clarification |
|---|---|---|
| Identity | Label name, product code and lot | Different names or unmatched lot |
| Document | Issuer, issue date and version | Unclear source, missing page or revision |
| Test | Attribute and method reference | A percentage with no named test |
| Result | Value, units and acceptance criterion | Result and criterion use different bases |
| Supporting file | Filename and matching lot | An unrelated chromatogram or spectrum |
Decide what remains unresolved
List gaps individually. For example: “Please confirm whether document version B applies to lot ___ and provide the method reference for the reported purity.” This gives the supplier a specific question and gives your laboratory an auditable answer.
Keep the original file alongside the response. Follow your laboratory’s release procedure; this checklist does not establish suitability for a particular experiment, sterile use or human use.
Continue the documentation check
A COA and a safety data sheet answer different questions. Read COA versus SDS and material identifiers before relying on a short catalogue name.
Source context: ICH Q7, section 11.4 describes certificates in an active pharmaceutical ingredient quality framework. The receipt checklist above is a practical organisational aid; citing that framework does not certify Aminovera products or make research material a medicine.
