Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. [1] Specialists in this field have a wide array of methods and instruments to help identify unknown substances.

Forensic toxicology is a multidisciplinary field that combines the principles of toxicology with expertise in disciplines such as analytical chemistry, pharmacology and clinical chemistry to aid medical or legal investigation of death, poisoning, and drug use. [1] The paramount focus for forensic toxicology is not the legal implications of the ...
Grounded in principles of physics, biology, chemistry, and medicine, bloodstain pattern analysts use a variety of different classification methods. The most common classification method was created by S. James, P. Kish, and P. Sutton, [4] and it divides bloodstains into three categories: passive, spatter, and altered.
Although ignitable liquids are the most common fire accelerants, other chemicals such as propane or natural gas could also be used to accelerate a fire. Detecting the use of a fire accelerant at a crime scene can be the difference between classifying a fire as accidental or as an arson. Once a case is determined to be an arson, the detection of ...
Luminol (C 8 H 7 N 3 O 2) is a chemical that exhibits chemiluminescence, with a blue glow, when mixed with an appropriate oxidizing agent.Luminol is a white-to-pale-yellow crystalline solid that is soluble in most polar organic solvents but insoluble in water.
The type of chemical that is used depends on the material the weapon is made of. These acids can range from Fry's Reagent for a magnetic metal, [ 21 ] which is a mixture of hydrochloric acid , cupric chloride , and distilled water , [ 29 ] to an acidic ferric chloride solution for a non-magnetic, non-aluminum material.
It is typically used to search for fingerprints on large non-porous surfaces that cannot be submitted for chemical development within a laboratory. [3] This particular method is best suited for the enhancement of freshly deposited fingerprints, because the adherence of the powder is diminished when the impression residue has dried.
