How to check this certificate
Check that the batch number on the report matches the one on your vial, because a report for a different batch says nothing about yours. Check that it names the laboratory and the company that commissioned it. And check that the chromatogram is there and legible, not a cropped summary.
Our guide to reading a peptide COA goes through each section, and what HPLC purity means explains the number everyone quotes.
