Candy Chromatography Background info: Paper chromatography is a logical technique used to separate works of a solution. Three examples of how we apply this technique to real-life would be: contaneminants in water‚ separation of plant pigmentation‚ and analysis of narcotics.

Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause the components of a mixture to migrate differently from a narrow starting point in a specific medium‚ in the case of this experiment‚ filter paper. It is used for the purification and isolation of various substances. There are two phases in chromatography: 1. Stationary Phase – a solid that does not move. In this experiment was the

Chemical Separation Introduction: The objective of this experiment was to extract the pigments from spinach leaves‚ perform Thin Layer Chromatography (TLC) on the spinach leaf extract‚ and then determine the best solvent mixture to use to separate the pigments in the extract. The pigments are located inside the chloroplast walls in the cells of the spinach leaves. In order to obtain the pigments the cell walls must be broken down thus exposing the pigment containing chloroplasts. Upon

favorite candies? Chromatography can solve that for you. Chromatography is a separation technique used by scientists for separating both organic and inorganic compounds. There are four different types of chromatography: thin layer‚ liquid‚ gas‚ and paper‚ but for this lab paper chromatography will be used. Who invented chromatography? A Russian botanist named Mikhail Semyonovich Tsvet invented chromatography in 1901 while doing research on plant pigments. Why is chromatography so important? This

Beethoven’s Ninth Symphony also known as the “Choral” was first performed in Vienna in 1824. The Ninth Symphony probably one of the most popular of Beethoven creations. The Ninth Symphony had several listeners including those earlier listeners and people who heard and saw the great Beethoven in person. The words are sung by four vocal soloists and a chorus in the Ninth Symphony. The words were taken from the "Ode to Joy” a poem that was written by Friedrich Schiller. The Ninth Symphony by Beethoven

How Chromatography Helps The Human Race Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. “Chromatography is done by making of a mixture move past the solids‚ or across the surface of a solid‚ like paper. The mixture is poured onto a solid surface. As the different components of the liquid run down the solid‚ some of them move more slowly than other. A component
