A quick and automated method for profiling heroin samples for tactical intelligence purposes.

Area of Science:

• Forensic Chemistry
• Analytical Chemistry
• Computer Science

Background:

• Illicit drug profiling is crucial for forensic investigations.
• Classical methods for heroin analysis can be time-consuming.
• A need exists for rapid, automated comparison of drug samples.

Purpose of the Study:

• To present a novel computerized procedure for profiling and comparing illicit heroin seizures.
• To develop an automated system for rapid analysis of chromatographic data.
• To compare the efficacy of this method against traditional techniques.

Main Methods:

• Derivation and gas chromatographic separation of five major heroin constituents.
• Fully automatic data analysis using a PHP/MySQL database.
• Comparison of chromatographic profiles using the square cosine function against a large database.

Main Results:

• The system enables rapid comparison of a single heroin profile against hundreds of samples within seconds.
• The computerized procedure automates data analysis and database management.
• This method offers advantages over classical minor constituent analysis.

Conclusions:

• The developed computerized procedure provides an efficient and rapid method for heroin profiling and comparison.
• Automated analysis and database comparison significantly enhance forensic casework.
• This technique represents an advancement in the forensic analysis of illicit substances.
