HPLC vs Mass Spectrometry: How Purity and Identity Are Verified
When a research peptide is described as “verified,” two analytical techniques usually sit behind that claim: high-performance liquid chromatography (HPLC) and mass spectrometry (MS). They answer different questions, and a credible verification process uses both. Here’s what each one actually does, in plain terms. HPLC: measuring purity High-performance liquid chromatography separates the components of a… Read more
