Analytical chemistry plays a vital role in forensic science by providing the tools and methods to identify substances found at crime scenes. Techniques like chromatography, mass spectrometry, and spectroscopy allow forensic scientists to analyze blood, hair, soil, and drugs, helping to establish evidence in criminal investigations. For instance, the analysis of fingerprints or bloodstains can determine their chemical composition, and toxicology tests can identify substances present in bodily fluids. Analytical chemistry ensures the accuracy and reliability of forensic evidence in solving crimes.
