THIS PAPER DESCRIBES THE ANALYTICAL TECHNIQUE OF FLAMELESS ATOMIC ABSORPTION FOR THE DETECTION OF BARIUM, ANTIMONY, AND LEAD RESIDUE ON COTTON SWAB WIPINGS FROM THE HANDS OF PERSONS SUSPECTED OF HANDLING A GUN.
Abstract
THE APPARATUS, EXPERIMENTAL PROCEDURE, AND TEST RESULTS OF THE FLAMELESS ATOMIC ABSORPTION TECHNIQUE ARE OUTLINED. IT IS CONCLUDED THIS TECHNIQUE IS BOTH SIMPLE AND SENSITIVE, AND THAT THE SMALL VOLUME OF SAMPLE REQUIRED IN THE ANALYSIS AND THE SIMPLICITY IN THE WIPING AND EXTRACTION PROCEDURES ALLOW THE TECHNIQUE TO BE EASILY ADAPTED FOR FIELD AND LABORATORY WORK IN CRIMINAL INVESTIGATIONS. THE ADVANTAGES OF THIS SYSTEM OVER OTHER TECHNIQUES FOR DETECTION OF GUNSHOT RESIDUE ARE LISTED.
