Gas Chromatography

Clarity Through Separation and Detection

Gas Chromatography (GC) separates the organic chemical components (analytes) of a mixture and detects how much of each is present or whether they are present at all. GC works best when analytes are volatile and thermally stable, so they do not degrade in the GC system. It separates based on boiling point and affinity for the column’s stationary phase. Industries including food & beverage, cosmetics, pharmaceuticals, consumer products, and chemicals rely on GC for quality control, research, and detecting volatile analytes in complex matrices.

How Gas Chromatography Works

A sample is vaporized and carried by an inert gas through a column. Components travel at different rates depending on volatility and interaction with the stationary material. As each component exits the column, a detector measures its presence and quantity.

Application

Practical Uses of Gas Chromatography:


  • Identify unknown organic compounds in mixtures
  • Analyze residual solvents, alcohols, or volatile monomers
  • Examine extractables, leachables, or odor/flavor profiles

Benefits

Why This Technique Matters:


  • Provide precise detection of volatile analytes for safety and compliance
  • Deliver reliable results for trace compounds in complex samples
  • Offer fast turnaround suitable for quality control and method development
