Chromatography

This is the name given to the spatial separation of mixtures of substances between two phases. There is liquid and gas chromatography (depending on the aggregate state of the medium used to transport the mixture). The stationary (separating) phase, which exists alongside the mobile phase, usually consists of a solid.

Three distinctions are common in liquid chromatography:

  • Thin layer chromatography
  • Column chromatography
  • paper chromatography.

The separation is based on the different interaction of the molecules of the separation phase and the mixture. Another common special chromatography method is gel chromatography, which is based on a pure filter/sieve effect.
