Reversed-phase HPLC with UV detection determines peptide purity as a percentage and identifies impurities, while LC-MS with high-resolution accurate mass confirms the peptide's identity by comparing observed molecular weight to the expected value. Both tests are performed on the same sample and delivered on a single Certificate of Analysis.

    Sample Requirements:

    • Minimum 5 mg for Purity & Identity (HPLC + Mass Spec)

    • Minimum 10 mg if adding Net Peptide Content analysis

    • Minimum 1 vial / 1 mL for HGH samples (dimer analysis available as add-on)

    • For conformity/variance testing, submit one vial per unit — each is tested separately

    • Label each vial clearly with its sample ID and lot number

    • Include a printed copy of the intake form in the shipment
