Chromatographic & Mass Spectrometry Methodology

Every released peptide batch is assayed against certified analytical reference standards utilizing calibrated European pharmaceutical protocols.

C18 RP-HPLC Purity Analysis

Reversed-phase high-performance liquid chromatography using porous octadecylsilane (C18) columns (4.6 × 250 mm, 5 μm) with binary gradient elution (acetonitrile / 0.1% TFA aqueous). Dual diode-array detection (DAD) at 214 nm and 220.4 nm enables baseline peak resolution of peptide impurities and diastereomers.

ESI-MS Molecular Verification

Electrospray Ionization Mass Spectrometry (ESI-MS) coupled with high-resolution quadrupole time-of-flight (Q-TOF) analyzers. Accurately determines monoisotopic molecular weight within ±0.5 Da, validating amino acid sequence fidelity and confirming absence of truncation artifacts.

Cryptographic Serialization

Each synthesized batch is assigned a unique cryptographic verification identifier recorded in this immutable public repository. Tamper-evident seals on every borosilicate vial match physical lots with certified laboratory release data.
