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

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
