Forensics: Chromatography

Chromatography is a vital technique used in various fields such as forensics, sports regulation, and environmental research. It helps in identifying specific dyes in fabrics, testing for illegal drugs, and detecting pollutants. Paper chromatography is a simple method using blotting paper and water to separate mixtures, while gas chromatography uses a gas carrier for more complex analyses. This technique is crucial for checking food purity, forensic investigations, and detecting explosives, making it an essential tool for analyzing chemical mixtures.
