Understanding Peptide Purity
When purchasing research peptides, you'll often see purity ratings like ">98%" or ">99%". But what do these numbers actually mean, and why do they matter?
What is HPLC?
High-Performance Liquid Chromatography (HPLC) is the standard analytical method for determining peptide purity. It separates compounds based on their chemical properties and measures their relative concentrations.
