Study Notes
Gas Chromatography
- Retention time in Gas-Solid Chromatography is determined by the interactions between the volatile compounds and the stationary phase.
Separation and Analysis
- Gas-Liquid Chromatography is the premier technique for separation and analysis of volatile compounds.
Gas-Liquid Chromatography
- The mobile phase in Gas-Liquid Chromatography is a carrier gas, which is an inert gas that flows through the column.
Separation Mechanism
- Van der Waals forces contribute to separation in Gas-Solid Chromatography.
Stationary Phase
- The stationary phase in Gas-Liquid Chromatography is a liquid adsorbed onto a solid support.
