Chromatography is a method used by scientists for separating organic and inorganic compounds so that they can be analyzed and studied. By analyzing a compound, a scientist can figure out what makes up that compound. Chromatography is used in many different ways. Some people use chromatography to find out what is in a solid or a liquid. It is also used to determine what unknown substances are. The Police, F.B.I., and other detectives use chromatography when trying to solve a crime. It is also used to determine the presence of cocaine in urine, alcohol in blood, PCB's in fish, and lead in water. Chromatography is used by many different people in many different ways.
We put a spot of ink near the end of a filter paper and hang the paper vertically with its lower edge dipped in a solvent which is usually alcohol or water. The solvent travels up the paper to the dissolved ink by capillary action . The mobile phase slowly travels up the paper and separates out the ink into different components.

We all know that green plants are green because they contain chlorophyll; we know that chlorophyll is green. Hang on; why are plants different shades of green if they all contain the same green pigment? Well, perhaps it is not quite as simple as you were told by your Biology teacher. In fact there are several different kinds of chlorophyll and some other photosynthetic pigments in green plants. So exactly what colour they are depends upon which types of chlorophyll and other pigments their leaves contain.
First, it's wet (or damp)
You put a charge on your sample
drop it on a sheet of special paper
set it in an emf (voltage) field
wait
then add dye.
the lighter molecules move further in the field than heavy ones do.
the patterns are reproducable and recognizable.
Paper chromatography is an analytical way to identify and separate mixtures. This method involves doing that by determining their pigments or the fact that they can be pigmented. This method can also be used in ink experiments.

Filtration Paper Chromatography Distillation
because when we usually test for a liquid or anything soluble we put a drop of it on the pencil line, then when we put the chromatography paper or filter paper in water the water will get on the paper and start moving upwards here when the water will approach the liquid or solvent or die and then they will move with water throughout the filter or chromatography paper.
The paper absorbs liquid
Chromatography You will need: Non- Waterproof markers like a white board marker (Preferably black) A Beaker with around 50mls of water Cello-tape Shreds of paper towel around the same width Method: Get your paper towel shreds, Put a line of marker pen across the paper towel at roughly the same height. Cello-tape the top of the paper towel to the beaker, Remembering which pen is which. Wait for the water to travel up the paper towel. The ink will seperate Vivid's don't work because their waterproof FAT markers from smiggle work really well!! Thanks, Tess Year 8
Hi is it got to do with Science? Its Chromatography .. Actually right now I'm studying Chromatography it's a really interesting unit. It is a way of seeing the other different colours that are mixed together to make that colour. As an experiment you have filter paper and because it has very small holes that you cannot see with a naked eye, liquids are most likely to be the only ones passing through. Anyway, anything that has to do with colour e.g food colouring, permanent marker etc... the filter paper will absorb the ink and will spread make sure the ink is about 2cm up your paper. You then dip the filter paper into a beaker of water - only about a cm full of water. After a few minutes the ink will naturally spread and you will be able to identify what other colours are used to create the colour of your chosen type of ink or whatever. They use Chromatography for like police investigations with DNA and that sort of stuff ...
whate is interpretation in paper chromatography
newspaper
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.
If you like science Paper Chromatography is something to look into. You can take Chemistry classes to find out different ideas on how to use Paper Chromatography.
Whatman Paper
There is no such thing as grass chromatography. there is only High Performance Liquid Chromatography, Gas Chomatography, and Paper Chromatography.
yes.
Coffee filter paper can be used. It does not produce results as good as chromatography paper, but it still works.
Paper chromatography is used as an analytical method not for production.
A non polar solvent will determine the distance in which a pigment moves up a paper. This will only work on chromatography paper.

A hypothesis for paper chromatography depends on what you are making the hypothesis on. A hypothesis for the speed of chromatography could be that you think the speed of the process can be changed depending on the type of paper, or whatever the stationary phase is, and the type of solvent being used.
