Understand the concept of chromatography: Chromatography is a technique used to separate mixtures into their individual components. It relies on the differential affinities of compounds towards a stationary phase and a mobile phase.

Identify the types of chromatography: Common types include paper chromatography, gas chromatography, and liquid chromatography. Each type uses different phases and mechanisms for separation.

Paper chromatography: This involves a stationary phase made of paper and a liquid solvent as the mobile phase. It is often used for separating pigments and small molecules.

Gas chromatography: This technique uses a gas as the mobile phase and a liquid or solid stationary phase. It is typically used for volatile compounds.

Liquid chromatography: In this method, a liquid mobile phase is used to pass through a column containing the stationary phase. It is widely used for a variety of compounds, including large biomolecules.
