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

In paper chromatography‚ some compounds in a mixture travel almost as far as the solvent does; some stay much closer to the base line. The distance travelled relative to the solvent is a constant for a particular compound as long as you keep everything else constant. Some compounds may travel farther than others because they may be composed of more components‚ thus traveling farther. For example‚ black is composed of every color of the rainbow‚ while yellow is composed of less colors. As a result

Anionic Exchange Ion Chromatography to Detect the Anions Concentrations in the water Samples Narendra Boppana‚ Nasser Ali‚ Martin Chavez‚ Sear Introduction: Ion Exchange Chromatography is a process where the ionic exchange occurs in between the stationary phase and the sample in the mobile phase‚ by using this ionic exchange phenomenon it is easy to separate the compounds. Ionic exchange depends on the electrical properties

Chromatography is the separation of compounds to allow us to see the different colours of that compound‚ for instance we may use chromatography in a school lab to see the real colour compounds of plants and grass‚ by using chemicals such as acetone we it will allow the object to break compounds and thus we can see the true colour of the grass. In today’s society there are many real world applications which use the chromatography technique in their line of work‚ an example of one of these applications

corresponding anthocyanidins using paper chromatography‚ and spectrophotometric analysis procedures. Based on experimental data the blueberries contained the most amount of anthocyanins at 1.92 x 10-6 g‚ followed by blackberries at 1.19 x 10-6 g‚ finally followed by raspberries at 5.84 x 10-7 g. The paper chromatography data also supports the idea that blueberries contained the most anthocyanidins‚ since it contained the most streaks on the chromatography paper. The main conclusion that can be

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

1. Should the Silicone-X project be undertaken? Why/why not? After completing the analysis and reviewing the NPVs and IRRs for each option‚ labor intensive and capital intensive‚ Soderberg should recommend that the Jacobs division move forward with production of Silicon-X using the labor-intensive option. The NPV and IRR methods make the same decisions if used for independent projects however‚ since these projects are mutually exclusive‚ the best NPV option should be used. In this
