Analytical Testing
HPLC, LC-MS and other laboratory techniques used to assess the purity and identity of peptide materials — plus how to interpret their outputs.
A plain-English walkthrough of how High-Performance Liquid Chromatography (HPLC) is used to measure peptide purity — from reversed-phase columns to peak-area interpretation.
How liquid chromatography-mass spectrometry (LC-MS) confirms the identity of research peptides, and why it is used alongside HPLC rather than instead of it.
Why a purity percentage on a peptide product page should never be interpreted in isolation — and what to look for behind the number.
An overview of the analytical techniques used to characterise research peptides — from HPLC and LC-MS through to identity, purity and stability testing.
