When people hear candy chromatography‚ they don’t know what to think about it. They of course know that it had something to do with candy. But just don’t know what. Candy chromatography is fun and simple. Candy Chromatography is a fun project‚ plus it has to do with candy. Candy Chromatography is an experiment to find out the true colors of the dyes in candy. When you put a skittle or an M&M in your hand in hot weather‚ the candy tends to bleed the color. And sometimes it shows more than one color

Gabriel Alizaidy Liquid Chromatography September 14‚ 2009 Objective: To separate the components of unsweetened‚ grape flavored Kool-Aid. Procedure: Using two syringes‚ inject different concentrations of alcohol to extract red and blue dyes‚ and artificial flavoring. Data: Conclusion: Different dyes are shown when separated by different concentrations of isopropyl alcohol. Discussion of Theory: Chromatography‚ resolution and selectivity played major roles in making the experiment work

Principles of Chromatography Substances present in a mixture are allowed to distribute themselves between two phases: the stationary phase (fixed) and the mobile phase. As the mobile phase flows over the stationary phase‚ components of the mixture experience many transfers

Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid

Gas Chromatography Purpose: The purpose of the gas chromatography lab is to find out how different substances interact with the surface of a solid. Chromatography is a separation technique that depends on the relative distribution of the components of a mixture between a mobile phase and a solid stationary phase. Chromatography measures the tendency of a substance to interact with the surface of a solid or to remain in a mobile phase. When doing a chromatography lab the mobile phase has to

com Liquid Chromatography AP Chemistry Laboratory # 18 Publication No. 10535A Catalog No. AP9093 Introduction In this experiment‚ liquid chromatography is used to separate the substances that are present in grape-flavored Kool-Aid®. First‚ the dyes responsible for the purple color‚ FD&C Blue #1 and Red #40 are separated. Then‚ in a second experiment‚ the other components of Kool-Aid®‚ the flavorings and citric acid‚ are separated as well. Concepts • Resolution • Liquid chromatography • Selectivity

Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly

The kermes dye was considered to be native to the old world‚ “Used by the Aztecs for dyeing and painting” (Douma‚ 2008)‚ and the Incas‚ who loved their reds. Throughout this time‚ various native american groups throughout Mesoamerica and South America used as dyestuff. It wasn’t until the 16th Century‚ that the Spanish conquest pushed the kermes dye into the hands of the Europeans. In fact‚ “When Spanish explorers discovered [the dye] and Conquistadors invaded Central and South America in the late
