Abstract
A process for the analysis of organic pollutants from an aqueous sample is provided including injecting an extraction solvent under pressure in the form of a plurality of substantially uniform droplets into the sample containing one or more pollutants. The solvent droplets are collected and then analyzed for the presence of the pollutants. The apparatus includes a sample holding column, a solvent reservoir, a source of gas under pressure, and a nozzle having one or more outlet ports which subdivides the solvent into small uniform droplets to enhance mass transfer of pollutants from the sample into the solvent.
