Paper Abstract

Forensic scientists have been, for several years, seeking a rapid, sensitive and relatively inexpensive analytical method for the quantitative determination of trace elements in gunshot residues. The "Paraffin Test" was introduced in 1935 and used for many years to identify deposits of nitrate and nitrites associated with gunshot residues. However, in recent years, the reliability of this technique has been questioned. Neutron activation has been applied to the determination of barium and antimony in gunshot residues. This technique has adequate sensitivity but has not gained widespread acceptance because of the expense and time required to complete the analysis.
