Every batch is independently verified for identity, purity, and molecular stability via HPLC and Mass Spectrometry before release. Search a batch number below or browse the ledger for the full certification.
Batch number is printed on the vial label and packing slip.
HPLC is the gold standard for quantitative purity analysis of synthetic peptides. Each sample is dissolved in a mobile-phase solvent and passed through a packed chromatographic column under high pressure, separating the target compound from synthesis-related impurities.
A UV detector at 220nm measures the absorbance of each eluting fraction. The ratio of the primary peak to total detected peaks determines percentage purity. AminoVita Research compounds must achieve a minimum of 99% before release.
Mass Spectrometry confirms the molecular identity of each peptide by measuring its exact molecular weight. The sample is ionized and accelerated through an electromagnetic field, and the mass-to-charge ratio is compared against the theoretical molecular weight of the target sequence.
This catches truncated sequences, oxidized variants, and structural anomalies that HPLC alone cannot identify — the two analyses together provide dual verification at the molecular level.
