What is a Certificate of Analysis?
A Certificate of Analysis (COA) is an official quality control document that confirms the identity, purity, and quality of a specific production batch. Every COA from 2DayPeptides includes HPLC chromatograms and mass spectrometry data verifying ≥99% purity for the exact batch that shipped with your order.
Testing Methods
HPLC Analysis
High-Performance Liquid Chromatography separates and quantifies compound components to verify purity at ≥99%. HPLC chromatograms are included in every COA document.
Mass Spectrometry
Mass spectrometry confirms molecular identity by measuring the exact mass of the compound. Identity verification is performed by independent third-party laboratories.
