Gas Chromatography: Separation and Analysis of a Mixture of Cyclohexane and Toluene Ashay Mehta November 30 th , 2009 Objective: To successfully separate and analyze cyclohexane and toluene by use of gas chromatography. Theory: Gas chromatography separates a sample into its component parts by putting the mixture in its mobile phase. They must go through or over the stationary phase. The components are distributed between these two phases depending on their affinity. If they have a greater affinity, then they will separate as they pass through system. In the mobile phase, the components will pass more rapidly than in the stationary phase. A detector at the end of the column records the quantity of each component. A flame ionization detector detects organic materials. As the materials burn, ions are formed in the flame and
