Chromatography - Lesson Summary
Chromatography is a technique that allows scientists to separate molecules of interest from a crude mixture. The purpose of chromatography is to separate a complex mixture into individual component exploiting the partition effect which distributes the molecules into different phases. In column chromatography, a stationary phase is filled into a cylindrical tube made up of glass or steel. The physical properties that can be used to separate molecules are: Molecular weightBoiling point
