Polar organic compounds in the river Elbe — Development of optimized concentration methods using substance-specific detection techniques

Different methods for solid phase extraction (SPE) of polar, organic compounds found in Elbe water were compared. Mass-spectrometric detection (MS) after liquid chromatographic separation (LC) or flow injection analysis (FIA) and thermospray ionization (TSP) was used to assess the concentration behaviour as well as the detection techniques. A selected compound was identified using tandem mass spectrometry (MS/MS) carrying out mixture analysis.
