  Also can be used to create vacancies 

Chromatography is useful in determining which antibodies fight various diseases and viruses. Scientists used Chromatography in the fight against the Ebola virus]]> 2018-01-26 12:04:35 UTC https://padlet.com/neo_si_lie_charles/9mn5zknxrtlr/wish/225011003 https://padlet.com/neo_si_lie_charles/9mn5zknxrtlr/wish/225093933 1.Cut a coffee filter into long strips(10 cm long)
-To soak up the water 
2.Use a black pen and draw a dot 2 cm away from the bottom
-This is the substances we are going to separate, link
3.Fill a cup with water and put the coffee strip into the water making sure
that the dot is above the water
-This is to allow the water to flow up the coffee filter and when it does it 
will leave pattern that that is how to identify the substances in the link by the color of the coffee filter that is above the original dot.]]> 2018-01-26 15:31:08 UTC https://padlet.com/neo_si_lie_charles/9mn5zknxrtlr/wish/225093933 https://padlet.com/neo_si_lie_charles/9mn5zknxrtlr/wish/225340183 It is important that the solvent level is below the line with the spots on it. Sometimes the paper is just coiled into a loose cylinder and fastened with paper clips top and bottom. The cylinder then just stands in the bottom of the container.
The reason for covering the container is to make sure that the atmosphere in the beaker is saturated with solvent vapour. Saturating the atmosphere in the beaker with vapour stops the solvent from evaporating as it rises up the paper ]]> 2018-01-28 03:41:31 UTC https://padlet.com/neo_si_lie_charles/9mn5zknxrtlr/wish/225340183 https://padlet.com/neo_si_lie_charles/9mn5zknxrtlr/wish/225368481 Paper chromatography is a method for separating dissolved substances from one another. It is often used when the dissolved substances are coloured, such as inks, food colourings and plant dyes. It works because some of the coloured substances dissolve in the solvent used better than others, so they travel further up the paper.A pure substance will only produce one spot on the chromatogram during paper chromatography. Two substances will be the same if they produce the same colour of spot, and their spots travel the same distance up the paper.

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 carries the mixtures with it. Different components of the mixture will move at different rates. This separates the mixture out.
