Gas chromatography (GC) is a technique used to separate, identify, and quantify volatile compounds in a sample by vaporizing the sample and carrying it through a column. The different components separate based on their interactions with the column material and are detected as they exit the column.
Industrial gases can act as carrier gases that transport samples through the column, detector gases, and makeup gases that optimize detector performance. Ultra high purity gases are essential to prevent contamination and ensure accurate results.
High-purity gases minimize baseline noise, reduce detector contamination, and improve peak resolution and sensitivity. They also extend column life and ensure consistent analytical results.
Helium is the primary carrier gas in most GC applications due to its chemical inertness, low density, and optimal flow characteristics. Its properties allow for faster analysis times and better peak resolution compared to other carrier gases.
Hydrogen is both an alternative carrier gas and as a detector gas in flame ionization detectors (FID). It offers faster analysis times and lower operating costs while maintaining good separation efficiency.
Nitrogen is a carrier gas for packed columns and a makeup gas that optimizes detector flow rates, while argon is used primarily as a carrier gas for electron capture detectors (ECD) and as a makeup gas.
Most GC applications require ultra high purity gases (99.999% or higher) to minimize impurities that could interfere with analysis. Common mixtures include hydrogen/air for FID operation and nitrogen/methane blends for specialized detection applications.
Proper ventilation, leak detection systems, and gas monitoring are essential because hydrogen is flammable and can displace oxygen. Regular maintenance of gas delivery systems, proper cylinder handling procedures, and emergency shutdown protocols help ensure safe laboratory operations.
