How to read this certificate
The identity result should be read alongside the laboratory method shown above. HPLC-RTM compares chromatographic retention time with a reference standard. Purity is reported by HPLC as a percentage of total peak area at a stated wavelength — a proportion of what the detector saw, not a proportion of the vial's mass. Net peptide content is the measured peptide amount in the tested sample. For a blend, the total does not establish each component's amount unless the laboratory reports those amounts separately.
A fuller explanation of each parameter is in how to read a peptide certificate of analysis, and the distinction between purity and net content is set out in purity versus net peptide content.
Check the batch number above against the number printed on the vial in front of you. If they do not match, this is not your certificate — search the certificate library for the number on your label.
