Chromatography is a chemical process through which scientist can separate mixed elements to analyze them individually.
It basically consists in dissolving the mixture in a liquid that separates the different elements as a purification process.
Forensic Scientists use it in different forms while processing samples, for example:
* Planar Chromatography that can identify if two samples are the same.
* HPLC that can detect explosive components and some specific drugs.
* Gas Chromatography can detect the presence of alcohol, drugs or poison in a body prior to its death.
