Zusammenfassung:	A computerized procedure is presented for profiling and comparison of illicit amphetamine seizures. The system involves an optimized capillary gas chromatographic separation step followed by peak identification by linear retention indices. An individual amphetamine street sample can be recognized after up to 14 identified characteristic peaks are mathematically compared with the data in an intralaboratory database via an exponential comparison algorithm. The procedure enables rapid screening: the GC analysis of an unknown sample and computer comparison against several hundred samples is performed in just over an hour.
