Area of Science:

  • Forensic Chemistry
  • Analytical Chemistry

Background:

  • Routine profiling of illicit heroin is crucial for casework.
  • Existing methods may lack efficiency or comprehensiveness.

Purpose of the Study:

  • To develop a straightforward method for routine profiling of illicit heroin samples.
  • To identify components derived from opium and adulterants in heroin samples.

Main Methods:

  • Sample pretreatment.
  • Gas chromatography on a capillary column.
  • Flame-ionization detection.

Main Results:

  • Successful identification of heroin components derived from opium.
  • Identification of various adulterants present in illicit heroin samples.
  • Discussion of statistical data for sampling and chromatographic analysis.

Conclusions:

  • The developed method provides effective routine profiling of illicit heroin.
  • The technique aids in identifying the origin and composition of seized heroin samples.
  • Data from 1986 samples highlight the method's practical application in forensic casework.
