Chromatography is the technique for the separation, purification, and testing of compounds.

The term “chromatography” is derived from Greek, chroma meaning, “colour,” and graphein meaning “to write.”

In this process, we apply the mixture to be separated on a stationary phase (solid or liquid) and a pure solvent such as water or any gas is allowed to move slowly over the stationary phase, carrying the components separately as per their solubility in the pure solvent.

What is Differential Extraction?

Differential extraction is the method of separation of any organic component present in an aqueous solution. In this process, we use an organic solvent for which the solubility of the desired compound is more as compared to that in water. Also, the organic solvent is chosen such that it is immiscible with the aqueous solution so that it can form layers and can be separated easily using a separating funnel.

The organic compound is later recovered by the process of distillation or evaporation. The process of continuous extraction is used in cases when the solubility of the compound is less in the organic solvent.
