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 any synthesis-related impurities.
A UV detector at 220nm measures the absorbance of each eluting fraction, producing a chromatogram where peak area directly corresponds to compound concentration. The ratio of the primary peak to total detected peaks determines the percentage purity of the batch.
All AminoVita compounds must achieve a minimum of 99% purity by HPLC before release. Batches that fall below this threshold are rejected and never enter our catalog.
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 resulting mass-to-charge ratio is compared against the theoretical molecular weight of the target sequence.
This analysis ensures that the compound is structurally intact and matches the expected amino acid sequence. It also detects truncated sequences, oxidized variants, and other structural anomalies that HPLC alone cannot identify.
Together with HPLC, MS provides a comprehensive dual-verification framework ensuring that every vial leaving our facility contains exactly what the label states — verified down to the molecular level.
