Certificates of analysis
One row per lot. Each certificate names the laboratory, the lot number printed on your vial, the identity test (mass spectrometry) and the purity result (HPLC). Download the PDF from the row.

How to read one of our certificates
A certificate of analysis is only worth the tests on it. Ours carry four: identity by mass spectrometry, which confirms the molecular weight matches the compound named on the label; purity by HPLC, expressed as the percentage of the peptide peak against all peaks; residual solvents, from the synthesis process; and bacterial endotoxin. Water and counter-ion content are reported where relevant because they explain why net peptide content is lower than the gross weight in the vial.
Each certificate carries the lot number that is printed on the vial label. If the numbers do not match, the certificate does not apply to your vial, and you should tell us.
Who does the testing
Lots are tested by an independent UK laboratory, independent of the manufacturer and of us. We publish the certificate as received, with the laboratory's name and report number, so it can be checked directly.
Until the first lots have been tested this page shows the specification for each compound with the lot marked as pending. No vial is dispatched without its certificate.
