HPLC COA Net Active Content & Underfill Decoder
Decode third-party lab Certificate of Analysis reports. Adjust your reconstitution math for quantitative mass variance, purity, and salt content to ensure exact research dosage delivery.
Certificate of Analysis Inputs
mg
The advertised mass printed on the vial label (e.g. 5mg, 10mg, 15mg).mg
Actual net peptide content measured by quantitative titration or mass spec.%
Peak area purity percentage reported on the chromatogram.Reconstitution Parameters:
Adjusted True Dosing Forensics
Corrected Syringe Draw Underfilled Vial (-14.0%)
58.6units (0.586 mL)
Drawing the standard unadjusted 50.0 units would result in an accidental 14.7% under-dose. Draw 58.6 units to deliver exactly 2.5 mg of active peptide.
True Active Peptide Mass8.53 mgvs 10 mg labeled
Actual Concentration4.27 mg/mLvs 5.00 mg/mL expected
HPLC Purity vs Net Peptide Content:A Certificate of Analysis showing 99.2% HPLC Purity only means that 99.2% of the organic compounds in the peak are the target sequence. It does NOT mean the vial contains 10.0mg of pure powder. Lyophilized peptides inherently retain 10–15% counter-ion salts (trifluoroacetate/acetate) and residual bound moisture. Always rely on quantitative mass spectrometry for precision calculations.
