[Comparative gas chromatographic studies of heroin samples. Results of a pilot project in West Germany in 1982].

From 1.4. -30.10.1982 all heroin samples weighing more than 5 g seized in the States of Baden-Württemberg, Hesse and by the Bundeskriminalamt were analyzed by capillary gas chromatography during a pilot project. For comparison of samples ratios of concentrations of heroin (including its decomposition products 0(6)-acetylmorphine and morphine) and its natural by-products of synthesis acetylcodeine, papaverine, and narcotine (noscapine) were determined. The application of these parameters and further qualitative and quantitative criteria for heroin comparison for investigative and legal purposes are discussed.
