In recent years, this same methodology has found increasing use in detecting and characterizing pyrotechnic reaction residue particles (PRRPs). This is accomplished by collecting particulate samples from a surface in the immediate area of the pyrotechnic reaction. Suspect PRRPs are identified by their morphology (typically 1 to 20 micron spheroidal particles) using a SEM, which are then analyzed for the elements they contain using X-ray EDS. This will help to identify the general type of pyrotechnic composition involved. Further, more detailed laboratory comparisons can be made using various known pyrotechnic formulations.<\/p>\n<p align=\"left\"><strong>Keywords<\/strong>: pyrotechnic reaction residue particles, PRRP, primer gunshot residue, PGSR, scanning electron microscopy, SEM, energy dispersive spectroscopy, EDS, morphology, X-ray elemental analysis, forensics<\/p>\n<hr \/>\n<p><strong>Ref:<\/strong> Selected Pyrotechnic Publication of K.L. and B.J Kosanke, Part 6, (2001-2002), pp 12-25<br \/> (K6_12)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>K.
