Chromatography
www.soinc.orgLiquid chromatography uses liquids which may incorporate hydrophilic, insoluble molecules. Gas Chromatography is used in airports to detect bombs and is used is forensics in many different ways. It is used to analyze fibers on a persons body and also analyze blood found at a crime scene. In gas chromatography helium is used to move a gaseous
