Essay / Research Paper Abstract
15 pages in length. Understanding the nature of explosives – detection, identification, characterization – requires significantly more information than merely knowing the substance used in the aftermath of an explosion. The extent to which explosives derive their composition from country of origin, manufacturer and myriad other components is both grand and far-reaching; in order to come up with a definitive answer from post-explosion residue, investigators must have access to a collective of information. Bibliography lists 11 sources.

Unformatted sample text from the term paper:
explosives - defined as "gunpowder, powders for blasting, high explosives, blasting materials, fuses (other than electric circuit breakers), detonators, and other detonating agents, smokeless powder and any chemical compound or
any mechanical mixture containing any oxidizing and combustible units, or other ingredients in such proportions, quantities, or packing that ignition by fire, friction, concussion, percussion or detonation of any part
thereof may and is intended to cause an explosion..." (Anonymous, 2000) - derive their composition from country of origin, manufacturer and myriad other components is both grand and far-reaching; in
order to come up with a definitive answer from post-explosion residue, investigators must have access to a collective of information (Ballantyne, 2001). II. DETERMINING THE ORIGIN Plants that manufacture
explosives uphold their own individual product characteristics that make it virtually impossible to apply any kind of broad brush during the identification process. The amount and type of impurities,
additives and by-products play an integral and synergistic role in the ability to identify explosives, which are highly dependent upon impurities present in the solvents and raw materials, as well
as the overall manufacturing process and the attributes of planned additives. Typically, each type of explosive maintains a by-products profile that aids in the ultimate detection of any given
explosive. Inasmuch as "the amount of these by-products, impurities and additives is very small" (Ballantyne, 2001), highly sensitive equipment is often used - particularly in the case of suspected
terrorism - in order to tap into areas where ordinary human methods fall short. III. NUCLEAR MAGNETIC RESONANCE & INFRARED (IR) SPECTROMETRY
Nuclear magnetic resonance (NMR) spectrometry is particularly important in defining organic chemicals; when combined with mass spectrometry (MS), the identification of nearly any chemical substance is all but guaranteed.
