Understanding COAs
A Certificate of Analysis (COA) provides critical information regarding the identity and purity of a synthesized peptide. HPLC (High-Performance Liquid Chromatography) determines the purity by separating the peptide from synthesis impurities (such as truncated sequences). Mass Spectrometry (LC-MS) confirms the identity of the peptide by measuring its exact molecular mass, ensuring the correct amino acid sequence was synthesized.
