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

This essay is based on the Premium Oil and Gas Company (POG) case study. POG‚ as a global‚ company is functioning in diversified business environment. It causes in fact‚ a necessity to deal with varied internal and external environmental issues‚ that occur within the company. Internal business environmental issues are in control of the enterprise. External business environmental issues‚ on the other hand‚ are driven by factors‚ that are beyond the control of the company (e.g. legal issues). According

Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment‚ chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However‚ nowadays‚ both coloured and colourless compound are used in chromatography by various methods. In chromatography‚ the separation process of mixture is mainly based upon the polarity and molecular weight of sample

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
