May 23, 2018· The physical processes of separating mixtures by filtration, evaporation and crystallisation are key to many industrial and research purposes. For example, water purification, edible salt production and pharmaceutical formulation require aspects of these techniques. Research chemists preparing new substances will frequently use these processes.

Read MoreApr 30, 2021· Chromatography is a way to look at complex mixtures by separating them into their components. The separation of a mixture into its components is a physical process; that is, because the components of the mixture are not chemically combined, they can be separated by physical means.

Read MoreChromatography was first devised in Russia by the Italian-born scientist Mikhail Tsvet in 1900. He developed the technique, he coined chromatography, in the first decade of the 20th century, primarily for the separation of plant pigments such as chlorophyll, carotenes, and xanthophylls.Since these components separate in bands of different colors (green, orange, and yellow, respectively) they ...

Read MoreThis month''s experiment is more of a challenge to see if you are able to think of ways to separate several different mixtures. The challenges are listed after the materials. Before you get started, list as many different ways as you can think of to separate the mixture.
Read MoreChromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid (gas, solvent, water, ...) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which is fixed a material called the stationary phase. The different constituents of the mixture have different affinities for the stationary phase.
