    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.
