Glass capillary gas chromatographic methods for profile analysis of trace impurities of illicit heroin samples have been developed. The procedure consists of extracting the impurities by toluene from acidic solution and examination by capillary GC. Derivatized and nonderivatized extracts of illicit heroin from different sources are reported. The reproducibility of the procedure and the detection with FID and N-FID are studied. Results obtained by application of the profiling procedure, as an additional pattern for comparison of samples in forensic casework, have shown the distinct advantage of this method.
