Electrochemical Detection of Polyamines Using Immobilized Enzyme as Post-Column Reactor in High Performance Liquid Chromatography

Abstract
Novel detection method of biological polyamines was developed. Polyamine oxidase immobilized column worked as a post-column reactor, in which hydrogen peroxide was produced. Then, hydrogen peroxide was electrochemically detected on a platinum electrode placed in down stream. The detection limit at the sub-pico mole level was obtained.
