Reading these certificates
HPLC purity is the share of UV-detectable material that elutes as the target compound; it is not the same as net peptide content, which also accounts for water and counter-ions. Identity means the measured mass matched the mass calculated for the compound. See how to read a certificate of analysis and HPLC and mass spectrometry explained.
