# Certificate of analysis

A certificate of analysis (COA) is a document issued for a specific batch of material reporting the results of quality-control tests against specifications. For research peptides it typically lists identity confirmation by mass spectrometry, purity by HPLC, appearance and batch or lot number, and may include net peptide content or water content.
