WebIon exchange chromatography is a specific type of separation based on net charge of the molecules being separated. The term HPLC refers to chromatography procedures carried out under high pressure, but the basis of the separation could be ion exchange, gel filtration, reverse phase, or affinity chromatography. Sponsored by The Penny Hoarder Webfraction. Each peak (lower chromatogram) exhibited a UV spectrum similar to p-coumaric acid (insert). Each of these peaks also showed mass extracted fragment ion peaks at 691 m/z (upper chromatogram).
