    Description / Table of Contents: Zusammenfassung An Hand von Modellverbindungen (Xylol, Toluol, Kresol, Dichlorphenol, Pyridin) werden Möglichkeiten zur Bestimmung organischer Wasserverunreinigungen gezeigt. Nach Konzentration der Stoffe durch Sorption an einem Styrol-Divinylbenzol-Copolymer und der Überführung in organische Lösung können die Komponenten mittels GC-MS identifiziert werden.
    Notes: Abstract By means of model compounds (xylene, toluene, cresol, dichlorophenol, pyridine) possibilities for the determination of organic substances in water are discussed. After a preconcentration by sorption on a styrene-divinylbenzene copolymer and transferring into organic solution analytical determination of the components is achieved by gas chromatography/mass spectrometry.

    Analysis of thermo-oxidation products of polypropylene and polyethylene by Gas chromatography/mass spectrometry (1976)
    Springer
    Fresenius' Zeitschrift für analytische Chemie 281 (1976), S. 23-27 
    Details
    ISSN: 1618-2650
    Keywords: Analyse der therm. Oxidationsprodukte von Polyäthylen, Polypropylen ; Chromatographie, Gas/Massenspektrometrie

    Topics: Chemistry and Pharmacology
    Description / Table of Contents: Abstract Thermal and thermo-oxidative degradation of polyethylene and polypropylene is discussed. The products of thermal and thermo-oxidative degradation are analysed using a GC-MS after previous adsorption in a column containing a sorbent of styrene divinyl benzene copolymer type. Aldehydes are the products mostly resulting from the thermo-oxidation of polyethylene and methyl ketones are those resulting from the thermo-oxidation of polypropylene.
    Notes: Zusammenfassung Der thermische und thermisch-oxidative Abbau von Polyäthylen und Polypropylen wird diskutiert. Die Abbauprodukte wurden mit Hilfe der GC-MS nach vorhergehender Adsorption an einer Säule aus Styrol-Divinylbenzol-Copolymer analysiert. Die thermischen Oxidationsprodukte des Polyäthylens sind meistens Aldehyde, die des Polypropylens Methylketone.
