Chromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. For example, solid-phase extraction is a kind of liquid chromatography in which different mobile phases are used in sequence to separate out different components of a mixture trapped in a solid phase. There are many different kinds of mixtures. Includes kit list and safety instructions. Explore how to separate mixtures using simple, hands-on chemistry experiments that show physical properties like size, magnetism, and density. Easy sketching for both students and teachers Once the components exit the column, the solvent can be removed by evaporation and the pure components can be further analyzed or identified. A separation process uses the different properties of a mixture’s parts to get them to separate. Separating mixtures If you’ve ever baked a classic Australian pavlova from scratch, you may have felt like you were performing a kind of science experiment.
