Chromatography

Chromatography is a laboratory technique used to separate mixtures into their individual components. It is widely used in various scientific fields, including chemistry, biochemistry, and environmental science.

Principles of Chromatography

Chromatography relies on the differential distribution of the components of a mixture between a stationary phase and a mobile phase. The stationary phase can be a solid or a liquid, while the mobile phase is typically a liquid or a gas.

Types of Chromatography

There are several types of chromatography, including:

• Thin-layer chromatography (TLC)
• Gas chromatography (GC)
• Liquid chromatography (LC)
• High-performance liquid chromatography (HPLC)

Applications of Chromatography

Chromatography is used in various applications, such as:

• Separation of amino acids and proteins in biochemistry
• Analysis of environmental pollutants
• Determination of drug purity in pharmaceuticals
• Quality control in the food and beverage industry
