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.

Why should the water be below the pencil line in chromatography?
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.
How does a paper towel work?
The paper absorbs liquid
What are some fun science expirements?
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
What is a chromtography?
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 ...
What is used as the stationary phase in paper chromatography?
The stationary phase in paper chromatography is the paper itself.
Which dyes adhere best to chromatography paper?
Dyes that are more polar tend to adhere better to chromatography paper because they interact more strongly with the cellulose fibers in the paper. Therefore, water-soluble dyes like food coloring or ink tend to work well for paper chromatography.
How is paper chromatography used in everyday life?
it can be used in everyday life by liquid chromatography, gas chromatography, thin-layer chromatographyand paper chromatography.
What are the two types of paper chromatogaphy?
The two types of paper chromatography are ascending chromatography, where the solvent moves up the paper, and descending chromatography, where the solvent moves down the paper.
What can you use instead of chromatography paper in a paper chromatography test?
Instead of chromatography paper, you can use materials like coffee filters, filter paper, or even paper towels for paper chromatography tests. These alternative materials can absorb the solvent and help separate the components of a mixture based on their solubility and molecular properties, similar to chromatography paper.
Where may one learn about 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.
Are paper and thin layer chromatography types of planer chromatography?
yes.
Can paper chromatography be used to separate large amounts of solutions Why or why not?
Paper chromatography is used as an analytical method not for production.
What are the key differences between paper chromatography and thin layer chromatography?
Paper chromatography and thin layer chromatography are both techniques used to separate and analyze mixtures of substances. The key differences between them lie in the materials used and the method of separation. In paper chromatography, a strip of paper is used as the stationary phase, while in thin layer chromatography, a thin layer of silica gel or other material is used. Additionally, in paper chromatography, the solvent moves up the paper through capillary action, while in thin layer chromatography, the solvent is applied directly to the stationary phase. Overall, thin layer chromatography is faster and more efficient than paper chromatography, but both techniques have their own advantages and applications in analytical chemistry.
What are some possible alternatives for paper chromatography?
Some possible alternatives for paper chromatography include thin-layer chromatography (TLC), gas chromatography, high-performance liquid chromatography (HPLC), and capillary electrophoresis. These techniques offer different separation mechanisms and have varying applications depending on the analyte and desired outcome.
Why do you crush leaves in paper chromatography?
Crushing leaves in paper chromatography helps to release pigments from the cells, making them available for separation on the chromatography paper. This allows for a more accurate analysis of the different pigments present in the leaves.
Where the paper chromatography discovery at?
