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

Anionic Exchange Ion Chromatography to Detect the Anions Concentrations in the water Samples Narendra Boppana‚ Nasser Ali‚ Martin Chavez‚ Sear Introduction: Ion Exchange Chromatography is a process where the ionic exchange occurs in between the stationary phase and the sample in the mobile phase‚ by using this ionic exchange phenomenon it is easy to separate the compounds. Ionic exchange depends on the electrical properties

These results reported are used to identify the unknown compound. In this experiment‚ chromatography and titration were performed to identify the unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin

Chromatography of Commercial Analgesics Using the thin layer chromatography the major components of a commercial analgesic tablet will be indentified and purified. The active ingredients of the analgesic used were characterized by comparison with chromatograms of aspirin‚ acetaminophen‚ ibuprofen‚ mefanemic acid‚ and caffeine through the use of UV chromatography then the Rf value was calculated for each solvent. INTRODUCTION In this experiment‚ thin-layer chromatography (TLC) will be used

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

Background Less than two years from its first release‚ Candy Crush Saga has become the first game that ranked as No. 1 on iOS‚ Android and Facebook at the same time. On Facebook alone‚ the Candy Crash Saga has 150 million active monthly users according to Facebook App Center. Players are so addicted to it that they have left their children stranded at school‚ abandoned housework and even injured themselves as they try to reach new levels of the game (Docketerman‚ 2013).
