Gas Chromatograph (GC)

Separates volatile chemical mixtures in a carrier gas stream through a capillary column.

Core Principles & Analysis

• Separates volatile compounds by their partitioning between a carrier gas and a coated capillary column.
• Uses inert carrier gases such as helium or nitrogen to sweep vaporized samples through the column.
• Often coupled to a mass spectrometer (GC-MS) for forensic and environmental trace analysis.

Specifications & Metrics

• MEASURES: Retention time separation
