Certificate of Analysis (CoA)
Also known as: CoA · certificate of analysis · COA
A batch-specific lab document reporting a compound’s identity and purity — the primary proof of what is in the vial.
A Certificate of Analysis (CoA) is a batch-specific document from an analytical laboratory that states what a product is and how pure it is. For a research peptide it typically reports identity (confirmed by mass spectrometry) and purity (measured by HPLC), against the claimed sequence and a minimum purity threshold.
It is the single most important trust document in the research-peptide category: without a CoA, purity and identity are only claims. A genuine CoA is tied to a specific manufacturing batch, not a generic marketing sheet.
Living Water Labs HPLC-verifies every batch and can supply the batch CoA on request.
