How we test
What every certificate covers.
01
Purity (HPLC)
Reverse-phase HPLC determines purity and detects impurities — the headline result on every certificate.
02
Identity (MS)
Mass spectrometry confirms molecular identity and weight against the expected sequence.
03
Per-Lot
Results come from an independent laboratory, so you can check the data for the peptide you ordered.
