PPT-Paper Chromatography

Introduction Chromatography is a widely used method of separating mixtures into their component parts Paper chromatography separates substances using two things called phases The first thing is chromatography paper also called the . Prepared by :. Mona . Abo. . Hasera. Chromatography. First application by M. S. . Tswett. 1903. For the separation of plant pigments. Since the components had different colors the Greek . chromatos. Separating . immiscible liquids. E. . Haniff. Objectives. Separate a mixture of different solutions using a given solvent (by difference of . solubilities. ). Separate a mixture of immiscible liquids. AP Investigation 5: Photosynthesis – Part I. Chromatography. T. echnique . used to separate a mixture into its component . molecules. The . molecules migrate, or move up the paper, at different rates because of differences in solubility, molecular mass, and hydrogen bonding with the paper. Chromatography. Chromatography is a technique of separation of different dissolved constituents of a mixture by absorbing them over an appropriate adsorbent material .It is a versatile method of separating different kinds of chemical mixtures .. Principle and Definition. Principle. The principle of chromatographic separation is very simple. The process is achieved by . distributing the substances. to be separated between a . mobile phase. and a . Experiment 6. BCH 333. [practical]. Objectives:. -. Separation . of amino acids using paper . chromatography and TLC.. :. Chromatography. -is the collective term for a set of laboratory techniques . for separate and identify the components of a mixture. Instrumentation. Invented by a Russian Botanist Mikhail . Tswett. in 1903 . He used chromatography . . to separate the colour . . pigments in plants from . . one another. Chromatography is a separation technique in which a mobile phase carrying a mixture moves in contact with a selectively adsorbent stationary phase. CLS 101: Chemistry For Nursing.
