Preliminary Study

Abstract Heroin samples from 100 actual cases were examined by multiple analytical techniques. After preliminary examination by microscopy and chemical analysis indicated similarity of questioned and known specimens, as many as 22 chemical elements were measured by neutron activation analysis and atomic absorption. Since illicit heroin is crudely produced, the qualitative elemental analysis is significant; however, more important for characterization purposes is the quantitative determination of the elements found because the concentration ranges for each element are extremely large.
