Analytical Documentation
Purity is the number every supplier prints. It is not the number that tells you how much peptide is in the vial. Here is what we publish, and what it means.
Learn MoreReported by HPLC, against a named method, tied to a lot.
Purity is determined by high-performance liquid chromatography, and the analytical method used is stated on the certificate rather than left implied. A percentage with no method behind it is not a result, it is a claim.
Identity is confirmed against a reference standard — verified, not assumed from what the label says.
Where a batch has been tested, the certificate is published here in full: lot code, test date, and every result the panel returned. Batch-specific Certificates of Analysis are available for applicable products, and a lot's certificate reports only the tests that lot actually received.
