TOPIC OVERVIEW

About Purity & COAs

Overview

This collection explains the role and limits of peptide purity claims and certificates of analysis. It covers chromatographic purity, identity confirmation, mass data, lot-specific records, laboratory attribution, test dates, and the difference between a reported percentage and a complete quality assessment. Analytical documents should be evaluated in context rather than treated as standalone proof of safety or suitability.

Topics covered
  • HPLC purity
  • mass spectrometry
  • identity testing
  • batch traceability
  • laboratory attribution
  • analytical limitations
Common names and related terms: peptide purity, peptide COA, certificate of analysis, peptide HPLC, peptide mass spectrometry, peptide testing
