A Spectrophotometric Detector for High-Performance Liquid Chromatography of Inorganic Polyphosphates

Abstract
A spectrophotometric detector for high-performance liquid chromatography of inorganic polyphosphates such as orthophosphate, diphosphate and triphosphate is described. This method is based on the employment of an air-segmented technique (AutoAnalyzer II, Technicon) as a detector, in combination with a post-column reaction using a molybdenum reagent.
