Exchange Chromatography Week 10 TAG Question 1: Chapter 6-4 of your technique book provides a detailed description of how to run a ion- exchange column. Assume you have a cation-exchange column already prepared and ready to use. Create an outline of no more than 10 steps describing how you will regenerate the column‚ load your sample and collect the hydronium ion released. 1. Open the stopcock at the bottom of the column and allow solution to drain out until the solution level in the column is

EXECUTIVE SUMMARY: The main objective of this project was to carry out a design on the Propane distillation column for a process that produces 1‚3 Butadiene. The raw materials used are Butane‚ Oxygen and Water and the process capacity is 100 000 tonnes per annum nominal. In the previous work it was stated that the plant is located in China. The main location of the plant is in the capital city of the Gansu Provence‚ Lanzhou. This was decided as the location over other provinces due to the excellent

able to experimentally analyze and isolate amino acids by separation techniques. One such method of separation is thin layer chromatography (TLC). In this method‚ a silica coated aluminum plate is spotted with the solution being separated‚ and the plate is placed in a developing jar containing a small amount of solvent. With time‚ the solvent

Abstract Wood columns of various lengths were tested for strength and their ability to buckle. Using a compression machine‚ multiple wood columns are placed into compression until their critical yield was reached and depending on the length‚ they can buckle or get crushed. A graph showing the critical load vs the slenderness ratio was used to display several results obtain from the experiment. Introduction The general aim of this experiment was to find whether the short‚ intermediate‚ and

Component seeks to separate‚ identify‚ quantify and analyze the active component found in Biogesic®‚ which may be useful for public awareness despite its wide acceptance and availability in the market. Furthermore‚ this study applies thin layer chromatography (TLC) technique since it is the simplest‚ cheapest yet most effective approach in terms to the study’s objectives. The TLC method implies Rf (Rate of flow) values where it is given by the distance from origin to center of subtance spot over the

Chromatography lab Purpose: To separate food colorings into their component dyes using paper chromatography. Materials: Chromatography paper‚ Food coloring‚ Ruler‚ Pencil‚ Solvent solution‚ Test tubes‚ Test tube rack. Safety precaution: wear aprons‚ to make sure that you don’t get any of the alcohol on your clothes‚ and if you break a test tube you don’t get glass on you. Procedure: See-attached handout. Results: See chromatography with Audrey’s lab report.
