Characterizing GLP-1 Therapeutics: Analytical Challenges and Solutions EU
Author(s)Waters Corporation
Semaglutide and tirzepatide are now household names, but behind every dose sits an analytical problem that small-molecule thinking can’t solve. Isomers share a mass, impurities hide in the tail of the main peak, and peptides cling to tubing, vials, and column hardware. Characterizing GLP-1 Therapeutics: Analytical Challenges and Solutions explores how separation scientists are responding. An expert Peer Exchange panel weighs up orthogonal methods, 2D-LC, inert hardware, and the role of AI in peptide method development. We trace the peptide revolution from Gila monster venom to a global surge in manufacturing capacity. And a new isocratic HPLC–DAD method shows that stability testing for both blockbuster peptides can be done in just three minutes.

"Perspectives in HPLC" examines 5 long-held HPLC "rules" (mobile phase filtration, routine buffer use, avoiding pH near an analyte's pKa, defaulting to 4.6-mm columns, and relying on AI for early method development), showing with experimental evidence that each is conditional rather than universally true in modern small-molecule drug testing.
