Experiment # 4 Paper Chromatography 1. Why is the chromatogram developed in an essentially closed system? - The chromatogram is developed in a closed system in order to prevent the solvent to evaporate. Most solvents used in the chromatograph are toxic and flammable. It is also put in a close system to reduce the chance of outside factors affect the chromatograph. 2. What is the main advantage of 2-dimensional paper chromatography over a 1-dimensional one? - The

Jessica Zebracki Organic Chem II Lab 2/15/15 Friedel-Crafts Acylation of Ferrocene and Column Chromatography Introduction: The intention of this lab is to analyze the formation of acetylferrocene using column chromatography. The Friedel-Crafts acylation reaction created acetylferrocene and diacetylferrocene‚ using phosphoric acid as a catalyst for the reaction between acetic anhydride and ferrocene (once applying heat). During column chromatography‚ a solution is passed through a filtration system

filtration is a non-adsorptive chromatography technique that separates molecules on the basis of molecular size. Desalting and buffer exchange are two special examples of gel filtration that are widely used in many downstream bioprocesses. Desalting is used to completely remove or lower the concentration of salt or other low molecular weight components in the sample while buffer exchange replaces the sample buffer with a new buffer. Gel filtration is one of the easiest chromatography methods to perform because
