Chromatogram & Sample Reference
HPLC Chromatogrammain peak 6.306 min

How to read this. Chromatographic purity is the percentage of total integrated peak area — how much of the detected material is the target peptide versus impurities. It is not a measure of net peptide mass content (what fraction of the powder is peptide versus counter-ion, water, or residual solvent). That mass content is measured separately and reported above as content per vial (mg net peptide). Results apply only to the sample submitted.
