Characterisation of Non-Volatile Organics from Water by Pyrolysis-Gaschromatography-Mass Spectrometrhe most important classes in the river Rhine. The combination of pyrolysis gas chromatography mass spectrometry is applied to the characterisation of these non-volatile compounds. The material is isolated from water and pyrolysed in a special inlet system for 10 sec. at 600/800°C. The pyrolysis prod

Analysis of Sulphonic Acids and Other Ionic Organic Compounds Using Reversed-Phase HPLColar organic compounds eg polynuclear aromatic hydrocarbons. The ionisation of sulphonated organic compounds must be suppressed either by the use of an ion-pairing reagent, by rendering the eluted solvent acidic, or by the use of more polar reversed-phase packings. The techniques employed for ionic

‘Around-the-Table’ Negotiationshniques are combined with the method of collisionally activated decomposition (CAD) in a tandem mass spectrometer a direct mixture analysis is possible. It will be demonstrated that this approach can be used to identify surfactants in surface water.
