  • Chromatography - 275 Words
    Chasyn Carter 1/8/13 Biology Chromatography Chromatography is the term for a set of lab techniques for the separation of mixtures. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The Russian-Italian biochemist Mikhail Semyonovich coined the term "chromatography" and published the first paper on the method in 1903. Chromatography has many uses in biology. It’s used to separate and identify...

    Chromatography: The colours separate and move up the paper at different rates Chromatography can be used to separate mixtures of coloured compounds. Mixtures that are suitable for separation by chromatography include inks, dyes and colouring agents in food. Simple chromatography is carried out on paper. A spot of the mixture is placed near the bottom of a piece of chromatography paper and the paper is then placed upright in a suitable solvent, eg water. As the solvent soaks up the paper, it...

    Chromatography (Greek for ‘colour writing’) is used to describe various methods applied to separate mixtures (referred to as the sample of the experiment) with great accuracy to analyze them. By using chromatography we can manipulate these to move at different speeds through the system, thus separating them. Chromatography is necessary in chemical industries, as well as bio processing companies. Chromatography can be: 1. analytical: used to measure ratios of analytes(substance in simpler...

    Paper chromatography is one of the easiest methods of chromatography. It is a method of planar chromatography (stationary phase is in form of a plane). Paper chromatography follows the basic principle of chromatography, which states that substances or components are distributed in between the stationary phase and the mobile phase. It is an analytical technique, where only a small amount of a sample is used for separating and identifying its components. Like any other method of chromatography,...

  • Paper Chromatography - 525 Words
    A solution of the mixture to be separated is "spotted", usually from a micropipet, near one edge of a piece of filter paper, and the solvent is evaporated. Usually several sample and standard spots are placed along the edge. Then the chromatogram is "developed" by immersing that edge of the paper in a solvent that migrates through the paper as the mobile phase. The solvent often has two, three or four components, one of which is usually water. Development is normally done in a chamber that is...

  • Thin Layer Chromatography and Column Chromatography
    Introduction Chromatography is a technique used to separate a mixture into its individual components. In this experiment, chromatography is done by using a thin layer chromatography (TLC) plate and filter paper. The word ‘chromatography’ itself means the separation of colours. However, nowadays, both coloured and colourless compound are used in chromatography by various methods. In chromatography, the separation process of mixture is mainly based upon the polarity and molecular weight of...

    Have you ever wondered how many dyes are in your favorite candies? Candy chromatography is a method of separating and comparing dyes used in candy. It is a complex mixture, without having to taste it. The word chromatography is broken into two Greek words, “ chroma” meaning color and ‘graphein’ meaning to write. It works because the components of the mixture will be different in how much they “stick” to each other, and to other substances. The dyes that stick more tightly to the paper fibers...
