What a Certificate of Analysis actually shows

A Certificate of Analysis (COA) is a document issued by an analytical laboratory that records what was tested, how it was tested and what the instrument measured. It is tied to a single batch, not to a product line.

A complete COA states the sample identifier, the date of receipt and analysis, the analytical method used, the instrument configuration where relevant, and the signature or reference number of the issuing laboratory.

A purity value on a COA describes the sample submitted to the laboratory on that date. It says nothing about other batches, later production runs, or storage after analysis.

If a supplier publishes a purity number without a corresponding signed report, treat the number as unverified. NAVYRA LABS publishes purity results only once the signed third-party report for that batch has been received.
