Research Peptide Purity Testing: HPLC and COA Guide
"Understanding peptide purity testing methods and how to interpret Certificates of Analysis for research purposes."
Purity testing is fundamental to research peptide quality assurance. HPLC (High-Performance Liquid Chromatography) is the gold standard method for verifying peptide purity, separating compounds based on molecular interactions to identify and quantify impurities. Mass spectrometry (MS) provides molecular weight confirmation. A Certificate of Analysis (COA) documents the results of these tests for each production batch. UK Peptides provides COA documentation for all products, with purity standards of 99%+ verified by independent testing.
