GC, Gas Chromatography

Understanding Gas Chromatography and Its Applications

Gas chromatography (GC) is an analytical technique used to separate and identify compounds in gaseous or volatile liquid samples. It works by vaporising the sample and passing it through a chromatographic column, where different compounds separate based on their interactions with the column material.

Typical applications for GC include:

• Environmental testing for pollutants and contaminants
• Quality control in pharmaceutical and food industries
• Petrochemical analysis for hydrocarbon profiling
• Forensic science and toxicology testing
• Clinical diagnostics and metabolite analysis

Key features buyers consider are column type and length, detector sensitivity (such as flame ionisation or mass spectrometry detectors), oven temperature control, and system automation capabilities.
