    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

    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

    Chromatography is the laboratory technique for separating mixtures into their components for analyzing, identifying, purifying or quantifying the mixtures or components. The mixture dissolved in the mobile phase (gas or liquid) is passed through the stationary phase (liquid or solid), which separates the analyte from the other molecules in the mixture. The differences in the migration rate of the compounds in these two phases effects the separation. Chromatography is either preparative or analytical

    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

    Chromatography and electrophoresis are used for many wonderful processes that take place in labs. Chromatography and electrophoresis are separation techniques employed by chemists. Chemists execute multiple chemical tasks daily therefore they must find the most efficient ways to carry out these functions. Even though electrophoresis has some benefits, Chromatography is more useful than electrophoresis because it is more versatile and can be widely used in research; chromatography should be used

    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 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

  • Chromatography of Dyes

    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

    Chromatography is a method used to separate the analyte that needs to be studied from the sample. Two phases include in this method that is stationary phase where it does not move and the mobile phase, which is the fluid that transport in the system. In mobile stage, the fluid can be liquid or gas contingent on the types of chromatography being utilized. In chromatography, the sample is first dissolved in the mobile phase before proceeding through the stationary stage. In stationary phase

  • The Importance Of Chromatography

    distribution between two phases is known as chromatography. One phase is typically a porous substance or stationary while the other one is fluid and will flow through the stationary phase. The components diffuse along the stationary phase in a general direction where the mobile phase is progressing. The rate of flow for the separate components is independent of the other samples on the paper, mostly dependent on the polarity of the mobile phase1. Chromatography is important because it is a widely used
