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 in an alcohol-water mixture. The observed percentage

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

Chromatography of Photosynthetic Pigments Abstract In this experiment a process of chromatography was used to separate chlorophyll a‚ chlorophyll b‚ xanthophyll‚ and beta carotene. When these pigments were obtained they were used to measure the wavelengths by way of spectrophotometer of each and the total of all the pigments wavelength. Introduction Photosynthesis is a process by which plants use the sunlight to convert it from light energy into chemical energy. This equation shows us how

Size Exclusion Chromatography Size Exclusion Chromatography (SEC) is the separation technique based on the molecular size of the components. Size exclusion chromatography is a kind of method to separate different size of molecules that put in solution. It was first discovered by two scientists who named Grant Henry Lathe and Colin R Ruthven. Both of them received the John Scott Award for this fabulous invention. There are various applications for Size exclusion chromatography such as biochemical

Chromatography • • • Separation based on polarity of compounds Two potential phases for a compound to exist in: mobile and stationary Partitioning of compounds between mobile phase and stationary phase occurs: o Compounds that are less polar move more in the mobile phase‚ those that are more polar “stick” more on the stationary phase o These polarity differences cause compounds move at different rates and therefore can be separated 1. Mobile Phase: the phase the moves; can be gas or
