Centrifugation is a method in which solid or liquid particles of different densities are separated by rotating them in the tube in a horizontal circle. Chromatography is a technique of separating the constituents of a mixture of liquids. It is also used for gases. This note contains information on chromatography, centrifuge and their application.
When two or more liquids having different boiling points are mixed, they can be separated by heating which is called distillation. Fractional distillation is a technique used when separating a mixture of two liquids that do not "behave" well enough to use simple distillation. This note explains about distillation and mixture.
