Evidence should follow the material
A quality claim is useful only when it can be linked to the material under consideration. Request a batch-specific certificate of analysis, the identity and assay methods, the relevant acceptance criteria and the report revision. Where chromatograms, mass spectra or additional test results are required, make those deliverables part of the agreed specification rather than assuming that a summary certificate includes them.
Purity, identity, active content, sterility and endotoxin are different attributes. One test does not automatically establish the others. The same care applies to company certificates: check the legal entity, site address, scope, issuing body and validity before treating a logo as evidence. The certificate collage supplied as a design reference has not been authenticated for this website, so its marks are not displayed as our qualifications. We publish verified batch documents only after review, and clearly identify gaps that still need supporting records.
| Document / test | What to check |
|---|---|
| COA | Batch match, material identity, methods, results, limits and authorization |
| HPLC / UPLC | Method, detector conditions, integration and suitability for the sample |
| MS identity | Expected and observed species, interpretation and sample traceability |
| SDS | Exact material, revision, hazards and handling instructions |
| Sterility / endotoxin | Separate validated test evidence if relevant; never inferred from purity |
| Quality-system certificate | Entity, site, scope, issuer, accreditation and validity |
Frequently asked questions
How can I request a CBL-514 COA?
Identify the exact material and batch and ask for the original report and required supporting data. This website publishes only reviewed records and does not invent a COA when no verified report is available.
Is an MSDS the same as a COA?
No. An SDS, formerly commonly called an MSDS, communicates material-specific hazard and handling information. A COA reports batch testing. Neither document replaces the other, and both must match the material.
