What a peptide COA can show

A certificate of analysis records findings for the sample named on that report. Depending on the requested method, it may report identity, measured quantity, purity or a combination of results. Report numbers and verification keys help readers check the document with the issuing laboratory.

How to assess a laboratory report

Check the compound name, labelled strength, task number, analysis date, measured units and the exact tests performed. A purity percentage alone does not answer every question about identity, quantity, sterility or suitability. Read the complete report and treat anything not measured as unknown.
