Purity, Potency & Identification
Lyophilized powder is reconstituted with purified water, diluted to ~500 mg/L, and analyzed by HPLC-UV-MS. Chromatographic purity is determined by area normalization. Peptide mass is quantified against an authenticated reference standard. Identity is confirmed by mass spectrum comparison.

Bacterial Endotoxins (LAL)
Reconstituted sample is diluted in endotoxin-free water and analyzed for bacterial endotoxins using the Limulus Amebocyte Lysate (LAL) method.
Ref: United States Pharmacopeia, National Formulary, General Chapter 85
Elemental Impurities (ICP-MS)
Reconstituted sample is diluted in deionized water and analyzed against known elemental standards by inductively coupled plasma mass spectrometry (ICP-MS).
