You have learned that mixtures are a physical combination of two or more substances. The substances in a mixture retain their unique chemical properties and can be separated by physical means. Filtration, boiling, distillation, and decantation are ways to separate mixtures. Another method is called chromatography. Chromatography was developed in 1910 by a Russian botanist named Mikhael Tsvet. Its name comes from two Greek words – chroma (color) and graph (writing). In chromatography, a mixture is passed through a special gas or liquid. The different substances in the mixture are attracted to the gas or liquid in different ways. The substances that are the least attracted separate from the mixture the fastest. The substances that are the most attracted take the longest to separate.
Chromatography is used by biochemists in labs and even forensic scientists at crime scenes. It can be used to analyze the substances in pollutants, separate blood proteins, and determine the ingredients in a flavor or scent.
