    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

    Candy chromatography is a method of analysis of separating and comparing of dyes used in candies and food coloring. It is also a proven method to analyze candy and its complex mixture‚ without having to taste it. These complex mixtures can be separated back into pure substances. To find out the ingredients of a favorite candy‚ chromatography would help to define every ingredient found in the candy sample. The word chromatography is derived from the two Greek words‚ "chroma" meaning color

    EXPERIMENT 5: CHROMATOGRAPHY Abstract Paper Chromatography uses a chromatogram paper as its stationary phase and the solvent as the mobile phase. Retention factor is the ratio of the distance travelled by the sample to the distance travelled by the solvent. This experiment aims to separate organic compounds‚ to compute Rf values and to identify unknown compounds using Rf values. The ten samples underwent paper chromatography to determine the components of the unknown sample. The mobile phase allowed

    Introduction Paper chromatography is a method using a chromatography paper to identify the many mixtures of one simple color. The word chromatography comes from the Greek words‚ "chroma‚" meaning color‚ and "grafein‚" meaning to write. The process of this experiment is to place a colored dot‚ such as marker ink‚ onto the chromatography paper‚ one centimeter away from the triangular tip. Next dip your chromatography paper into the solvent‚ not allowing it to touch the colored dot. Let it sit for
