    Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to...

    Gas Chromatography Part 1: General Questions 1. Gas chromatography is a type of chromatography that allows for separation and analysis of a compound. It does this by vaporizing the sample then using a carrier gas to push it through a column which then separates it based on an equilibrium formed between solution and dissolution. 2. As a gaseous mixture travels down the column parts of the sample dissolve into the liquid. There is equilibrium between the gas phase (solution)...
