Each category (like About the DPS), has multiple sub-categories. Some bullet coatings may also contain nickel. Another technique for analysis of GSR is inductively coupled plasma mass spectrometry (ICP-MS). (Vachon and Martinez, 2019) (Dalby et al, 2010), In the physical examination of the scene or body for evidence of gunshot residue, it must be remembered that lead residues may mimic gunshot residue. A commonly used lead-based primer contains the shock sensitive explosive lead styphnate, oxidizer barium nitrate, and antimony sulfide fuel, yielding residue metals lead (Pb), barium (Ba), and antimony (Sb). Bullet cores are most often lead and antimony, with a very few having a ferrous alloy core. Those test patterns are then compared to the evidence pattern. (Dalby et al, 2010).
