Analytical Testing Methodology

Our dual-testing protocol verifies both structural molecular identity and quantitative chemical purity before any compound is released.

Threshold: ≥ 99.0%
High-Performance Liquid Chromatography (HPLC)
Quantitative chromatographic purity assessment and trace impurity resolution.

Reverse-phase HPLC isolates the target peptide molecule from truncated peptide sequences, oxidation byproducts, and residual synthesis adducts.

Stationary Phase:C18 4.6×250mm, 5μm
UV Detection:214 nm & 220 nm
Accuracy: ± 1.0 Da
Mass Spectrometry (LC-MS) Identification
Exact molecular mass-to-charge (m/z) structural confirmation.

Electrospray Ionization Mass Spectrometry (ESI-MS) confirms that the primary amino acid sequence matches the theoretical molecular weight exactly.

Ionization Mode:Positive ESI (+)
Mass Tolerance:< 0.5 Da variance
