[A quickly methodology for drug intelligence using profiling of illicit heroin samples].
OBJECTIVE
The aim of the paper was to evaluate a link between two heroin seizures using a descriptive method.


METHODS
The system involved the derivation and gas chromatographic separation of samples followed by a fully automatic data analysis and transfer to a database. Comparisons used the square cosine function between two chromatograms assimilated to vectors.


RESULTS
The method showed good discriminatory capabilities. The probability of false positives was extremely slight.


CONCLUSIONS
In conclusion, this method proved to be efficient and reliable, which appeared suitable for estimating the links between illicit heroin samples.
