✦ Synopsis
Gel permeation chromatography with on-line multicomponent determination of analytes in the column effluent is described. The system includes simultaneous measurement of organic carbon, organic nitrogen and organic halogens based on segmented flow analysis and on-line UV oxidation. Quantitative recoveries of various organic model compounds were obtained. Additionally the diode-array spectrophotometric detection applied gives UV-visible absorption spectra providing fingerprints for the specific components present in water samples. The system was applied for characterization of wastewater from chemical industry.
