How Does Chemistry Relate to Forensic Science?
Chemistry is used in forensic science to uncover information from physical evidence. In criminal cases, chemists analyze substances such as blood, DNA and gunpowder residue to attempt to determine when and by whom the crime was committed. In civil cases, chemists analyze DNA to authenticate valuable products and to identify fraudulent activity. Chemists also determine information from unsolved crimes and mysteries of long ago through other means of DNA analysis. Blood Analysis Aside from being used for identification of suspects, the contents of blood on a crime scene can be evaluated to reveal the presence of substances. For this evaluation, a chemist will perform a chromatography test, which uses intense heat to separate the blood into different contents. Afterward, a chemist determines the level of substances such as alcohol or medication that would affect the suspect´s actions and motivations during a given crime.
