ABSTRACT:
A system for continuously measuring the concentration of organic compounds in an aqueous solution utilizes a first non-porous hollow fiber bundle having organic solvent flowing therethrough to extract organic compounds from a water sample into the organic solvent. The extractant can then flow through a second hollow fiber bundle where pervaporation of a fraction of the solvent takes place thereby increasing the concentration of organic compounds in the solvent extractant. The extractant then flows into a control unit which identifies and quantifies the organic compounds therein.
