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

away with this price for 5.5 oz because of less competition close to that amount of oz. Also‚ it helps keeping the image of quality. Could also consider producing the 10oz at a higher price maybe at 6.95‚ which is the highest competitor price for a gel and that one had less ounces. Could justify by differentiation on quality and features. This option will be very profitable of priced like this. • Consider developing your own retail distribution methods so you can cut on rack jobbers variable costs

experiment is to identify an unknown proprietary drug using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done

Characterization Essay By Amber Dennis The authors of the Spark notes series writes‚ “As an outsider‚ John takes his values from a more than 900-year-old author‚ William Shakespeare. John’s extensive knowledge of Shakespeare’s works serves him in several important ways: it enables him to verbalize his own complex emotions and reactions‚ it provides him with a framework from which to criticize World State values‚ and it provides him with language that allows him to hold his own against the formidable

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol

Separation techniques LIQUID CHROMATOGRAPHY ‘THE ART OF SEPARATION’ CHROMATOGRAPHY – AN INTRODUCTION Chromatography is a technique through which a mixture of chemical components are separated‚ identified and determined accurately. This technique while provides a way for analytical separations‚ also useful for preparative techniques by which pure compounds can be obtained.

mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their physical and chemical attributes‚ such as speed and weight. To easily picture the process‚ the example will pertain to a paper chromatography process in which the liquid is moving over the paper‚ separating

Fluorescent Protein (rGFP) from the E.coli strain using Ni2+ agarose affinity chromatography technology Abstract The purpose of this experiment was to express and purify the his6-tagged recombinant form of GFP (rGFP) from the organism E.coli using Ni2+ agarose affinity chromatography. The expression of rGFP was confirmed qualitatively using the UV light and was expressed in the E.coli strain BL21 (DE3) (-- removed HTML --) (-- removed HTML --) . Ni2+ agarose affinity chromatography was used to
