    • 2 Pages

    Chromatography of Dyes An extremely common technique by using two chemicals and filter paper can give you sufficient information. A well-done Chromatography of dyes will provide you with enough data to determine if a liquid mixture is heterogeneous or homogenous . In a learning activity you can separate and possibly identify food dyes in some drinks mixes and food colors. The effect of solvent polarity or the ability to separate and elute compounds will also be demonstrated. In this experiment

    Capillary Liquid Chromatography- Mass Spectrometry What is Chromatography? Chromatography is the technical term for a set of laboratory approaches for the separation of mixtures (Solid/Liquid/Gas). The mixture is dissolved in a fluid which called the mobile phase, which carries it through a structure holding another material known as the stationary phase. The various constituents of the mixture transport at different velocities, causing them to separate. The separation is mainly based on differential

    The term chromatography refers to different methods of molecular separation between a mobile phase and a stationary phase based on various physio-chemical properties. There are many types of chromatography that are used as analytical tools in environmental science, forensics, metallurgy, biology, etc. Some common examples are thin layer chromatography (TLC), gas chromatography (GC), high performance liquid chromatography (HPLC) and ion chromatography. Ion chromatography (IC) was introduced as an

    Chromatography is a method of separating and analyzing complicated substances. This is done in two phases, a mobile phase and a stationary phase .During the stationary phase, said substance is stationary, while during the mobile phase, the substance moves in a specific direction. During the mobile phase, the substance is filtered through the stationary phase. The stationary phase in necessary in order for the substances to be separated even though it doesn?t involve movement of the substance because

    Candy chromatography My experiment is called candy chromatography. This project is mainly about the colors that are mixed with other colors to make candy markers Koolaid and much more. I think that only the color of the candy is going to show up on the coffee paper. I think that threw the entire experiment the color in the candy is going to show up the entire time. I think this is going to happen because most of the colors are solid colors. The material and equipment used was a sample of candy

    Chromatography is a separation technique in which the mixture to be separated is dissolved in a solvent and the resulting solution, often called the mobile phase, is then passed through or over another material, the stationary phase. The separation of the original mixture depends on how strongly each component is attracted to the stationary phase. Substances that are attracted strongly to the stationary phase will be retarded and not move alone with the mobile phase. Weakly attracted substances will

    Tank Chromatography Introduction: Chromatography is a method used to separate both organic and inorganic compounds so that they can be analysed. Scientists often use chromatography to figure out which basic constituents makes up a specific mixture. Chromatography relies on the principle of selective absorption. A botanist named M.S. Tswett in 1906 first discovered chromatography. Tswett used a method called 'column chromatography' to separate chlorophylls by pouring petroleum-ether

    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

    Chromatography Investigation Chromatography is a highly regarded technique used to separate the components of a mixture. It is based on the principle that each component possesses a unique affinity for a stationary phase and a mobile phase. The components that are more inclined to enter the mobile phase will migrate further on the chromatogram and distinguish themselves from the other components. The type of solvent used in chromatography is known to directly affect the separation of the

    Bioaffinity chromatography is a type of affinity chromatography in which biological compounds such as immunoglobulin-binding proteins, enzymes, lectins, carbohydrates, avidin/biotin system and antibodies are used as ligands (Hage, 2006). Immunoglobulin-binding proteins, namely protein A which is produced by Staphylococcus aureus and protein G which is produced by streptococci, are the ligands that are used in the vast majority of bioaffinity chromatographic applications (Tetala and van Beek, 2010)
