The full evaporation technique (FET), which is a variant of headspace analysis used to overcome matrix effects, was combined with capillary gas chromatography (GC) and ion-trap detection (ITD). The aim was to enable quantitative tests of volatile organic compounds (VOCs) in blood and postmortem tissue samples. FET was applied to sample sized less than 35 mg(More)
This paper describes the analysis of ethanol in blood specimens from suspect drunk drivers and the associated quality assurance procedures currently used in Sweden for legal purposes. Aliquots of whole blood from two separate Vacutainer tubes are diluted with 1-propanol as internal standard before analysis by headspace gas chromatography (HS-GC) with three(More)
Using headspace capillary GC-MS with ion-trap detection, the additive in motor gasoline, MTBE (methyl tert.-butyl ether), was spotted in the blood from five victims of arsons set off with motor gasoline. In the brain from a death of a fire started by ignited isoparaffins, a number of branched C8 alkanes were found. Since 80 control samples of accidental(More)
Diethyl ether was found in samples of the blood, urine, and lung from a fire victim. Because the lung also carried a number of low-boiling paraffins, it was inferred that the detected compounds came from engine starting fluid, which the victim apparently had been exposed to while be intentionally used it as an accelerant to start the fire. The reported(More)
As shown by others, ethanol and methanol appear in the breath of normals, and endogenous methanol becomes detectable also in the blood after intake of ethanol. In this study I have investigated whether low-molecular-weight volatile organics, other than methanol, arise in the blood of drunk drivers who had imbibed alcoholic beverages. To this end a method(More)
