Gas Chromatography (GC) is an analytical instrument widely used for separating and analyzing volatile and semi-volatile compounds in mixtures. Its primary applications include:

1. Chemical Analysis

• Separation, identification, and quantification of components in complex mixtures.

• Used in environmental, pharmaceutical, food, and chemical industries for analyzing organic compounds.

2. Environmental Monitoring

• Detection and measurement of pollutants such as volatile organic compounds (VOCs), pesticides, and greenhouse gases in air, water, and soil.

3. Food Safety and Quality Control

• Analysis of food additives, contaminants, pesticide residues, and flavor compounds to ensure safety and compliance with regulations.

4. Pharmaceutical and Biomedical Applications

• Determination of active pharmaceutical ingredients (APIs), impurities, and metabolites in drugs.

• Used in drug development, quality control, and pharmacokinetic studies.

5. Petrochemical and Fuel Analysis

• Characterization of hydrocarbons and other compounds in crude oil, refined products, and fuels.

• Helps optimize refining processes and ensure product quality.

6. Forensic Science

• Detection and identification of illegal drugs, explosives, and other substances in criminal investigations.

7. Research and Development

• Used in academic and industrial research for studying chemical reactions, material composition, and complex mixtures.

8. Quality Assurance and Process Control

• Monitoring and controlling the quality of raw materials, intermediates, and final products in manufacturing processes.

How It Works

Gas Chromatography separates compounds based on their volatility and interaction with a stationary phase inside a column. A carrier gas (e.g., helium or nitrogen) transports the sample through the column, where components are separated and detected by a detector (e.g., FID, MS). The resulting chromatogram provides qualitative and quantitative information about the sample.
