Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

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 of silica‚ sand‚ and
