The separation of components is often performed prior to analysis. Analytical methods can be separated into classical and instrumental. Classical methods (also known as wet chemistry methods) use separations such as precipitation, extraction, and distillation and qualitative analysis by color, odor, or melting point.

Some of these separating techniques are filtration, centrifugation and decantation. Others include sieving, magnetic separation and sublimation, evaporation, crystallization, fractional precipitation, distillation, fractional distillation, using separating funnel and chromatography.

Some of them include column chromatography, thin-layer chromatography (TLC), paper chromatography, gas chromatography, ion exchange chromatography, gel permeation chromatography, high-pressure liquid chromatography, and affinity chromatography [6].

The chapter discusses simple separation methods, such as evaporation, filtration, distillation, and extraction. Simple methods such as evaporation and filtration have been used by scientists for a long time to achieve desired separations.

Physical Separation Methods - Filtration, Centrifugation, Magnetism, Evaporation and Distillation.

In winnowing, light weight impurities are separated from relatively heavier substances. For example, husk is separated from wheat. It is done by releasing the mixture into the air so that the wind blows away the lighter impurities, while the heavier grains fall back down for recovery.

Filtration is the method of separation in which impurities are removed from water by using filter paper. The solid impurity which we get on the filter paper is called a residue, and the water which passes through the filter paper and gets collected in a conical flask is called the filtrate.

Filtration or Sedimentation The most common method of separating a liquid from an insoluble solid is the filtration. Take, for example, the mixture of sand and water. Filtration is used here to remove solid particles from the liquid.
