Abstract
A screening method for detecting volatile hydrocarbons in blood has been developed using gas chromatography/mass spectrometry with a wide-bore capillary column and a headspace method. Toluene-d8 and indan were used as the internal standards for quantitative analysis. Hydrocarbons with retention indices from 600 to 1200 were simultaneously and quantitatively detected in relatively low concentrations (0.01 μg/ml) in reconstructed ion chromatography. This method could prove useful in forensic cases in which urgent examination of complex hydrocarbon mixtures, e.g. petroleum components, is required. Es wird über eine Screeningmethode zum Nachweis flüchtiger Kohlenwasserstoffe im Blut mittels Gaschromatographie/Massen-spektrometrie berichtet, wobei wide-bore Kapillaren und die Headspace-technik eingesetzt wurden. Toluol-d8 und Indan dienten als interne Standards bei der quantitativen Analyse. Kohlenwasserstoffe mit Retentionsindi-zes zwischen 600 und 1200 konnten mit der Ionenchromatographie simultan und quantitativ noch in relativ geringen Konzentrationsbereichen bis 0.01 μg/ ml bestimmt werden. In der Praxis ist die Methode nützlich, wenn es in forensischen Fällen darum geht, komplexe Kohlenwasserstoffgemische (wie z.B. Petroleum) rasch zu analysieren.Keywords
