What these results mean
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. A certificate reports only the tests run on this lot; endotoxin, sterility and contaminant panels are not part of standard lot release. How to read a certificate of analysis.
