title: A quick and automated method for profiling heroin samples for tactical intelligence purposes.
abstract: A computerized procedure is presented for the profiling and comparison of illicit heroin seizures. The system involves the derivation and gas chromatographic separation of five major constituents followed by a fully automatic data analysis and transfer to a PHP/MySQL database. Comparisons via the square cosine function between a single chromatographic profile and the whole database (several hundred of samples) are performed in a few seconds. Advantages of this profiling method compared to the classical minor constituents one are discussed.
