Chromatography is used in science as a method for separating mixtures and for detecting substances. During the production of drugs negative substances are separated from positive ones, and in the field of forensics offenders can be convicted on the basis of detected substances. In sports, athletes can be tested for doping using chromatography on a urine sample. An advantage for the school: The principle of the chromatography can be carried out with a few water-soluble fibre pens and simple kitchen paper.
