exchange Chromatography Ion exchange chromatography is a process for separating proteins and other molecules in a solution based on differences in net charge. Ion Exchange Chromatography relies on charge-charge interactions between the proteins in your sample and the charges immobilized on the resin of your choice. Ion exchange chromatography can be subdivided into cation exchange chromatography‚ in which positively charged ions bind to a negatively charged resin; and anion exchange chromatography‚ in

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

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.

Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

Ion 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

Division of Labor Introduction: The phrase “division of labor” has many different definitions that can be used in different contexts. The Encyclopedia of Sociology helps explore the many different ways division of labor can be defined‚ and recognizes that all major sociologists considered this topic to be fundamental in understanding modern society‚ and how it has came to be. (Borgatta Montgomery and Rhonda 2000). Some of these classical sociological thinkers expressed their own ideas of division
