Applications of Gas Chromatography: Gas chromatography (GC) is another type of analytical technique used for separating, characterization, quantization, and identification of volatile compounds. It can be used in many different fields such as; pharmaceuticals, cosmetics, and even for environmental toxins. The powerful separation efficiency and sensitive detection make GC a useful tool for the analysis of essential oils from herbal drugs. In GC, the mobile phase is an inert gas such as; helium or nitrogen, or hydrogen. The stationary phase is usually a layer of liquid or polymer-supported on inert solid material inside a column made of either glass or metal column.
Applications of Gas Chromatography
- Gas Chromatography can be used to determine the identity of herbal products containing complex mixtures of similar compounds.
- It is most suitable for the separation and analysis of volatile compounds such as; essential oils and fatty oils.
- It is used in the analysis of foods like; carbohydrates, proteins, lipids, vitamins, steroids, drugs, pesticide residues, and trace elements.
- Pollutants like; formaldehyde, carbon monoxide and DDT can be analyzed.
- It serves both qualitative and quantitative purposes.
- It is used in the analysis of dairy products for rancidity.
