Certificate of Analysis library
WholesalePeptide.us publishes a Certificate of Analysis for every lot it ships. A lot-specific Certificate of Analysis is published before the lot ships. Every certificate in this library is issued by an independent third-party laboratory and reports RP-HPLC (UV 214/220 nm) and LC-MS identity, net peptide content and the test date for one lot. The lot code printed on each kit matches exactly one certificate here; the purity floor for release is 99%.

COA FAQ
What is a peptide Certificate of Analysis?
A COA is the lab report for one production lot. Ours states the lot code, RP-HPLC purity with the chromatogram, LC-MS identity (observed vs. theoretical mass), net peptide content, the test date and the name of the lab (an independent third-party laboratory).
Is the COA for the exact vials I receive?
Yes. Every kit label carries a lot code, and A lot-specific Certificate of Analysis is published before the lot ships. Search this library by lot code to match a certificate to your kits.
How do I read a peptide COA?
Check the lot code matches your label, the HPLC purity and chromatogram, that the LC-MS mass matches the theoretical mass for the sequence, and the net peptide content. Our guide to reading a peptide COA walks through each field.
