What Is Forensic Chemistry?
Forensic chemistry is a branch of chemistry that applies analytical techniques and scientific knowledge to criminal investigations. It involves identifying unknown substances, analyzing materials from crime scenes, and interpreting chemical evidence to support or refute hypotheses in legal settings.
In Elkins’ book, forensic chemistry is not merely defined by laboratory analysis. Instead, it is illustrated as a dynamic, interdisciplinary science that combines analytical rigor with investigative curiosity.
