The solvent rises up the chromatography paper (blotting paper) by capillarity. When the solvent reaches the "spot" it dissolves the mixture of coloured chemicals. There is now a solution; this is a mixture of solutes dissolved in the solvent. The molecules of these different chemicals are all different sizes. The simple explanation is that the smallest solute molecules travel almost as quickly as the solvent molecules and so get carried to the top of the chromatogram. The largest solute molecules travel very slowly and stay near the bottom. So some of the coloured chemical travel further than others. If you are doing this with amino-acids you will not see anything happen until the end of the experiment when you stain it with ninhydrin.

What are some possible alternatives for paper chromatography?
Coffee filter paper can be used. It does not produce results as good as chromatography paper, but it still works.
What pen works best on chromatography?
Dark colors like black and brown.
How can chromatography separate out the different pigments in the paint?
Chromatography works by separating inks into the different colours they are made of. You see, the paint is a solute and if it is added to a solvent and dissolves you have a solution.
What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
Which property of compounds is responsible for the separation in TLC?
The general Principle involved in tlc is similar to that of column chromatography i.e. adsorption chromatography. In the adsorption process, the solute competes with the solvent for the surface sites of the adsorbent. Depending on the distribution coefficients, the compounds are distributed on the surface of the adsorbent.
What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
What is the scientific name for all owls?
...how do you think scientific nomenclature actually works? the point of a scientific name is to separate between species. there are multiple species of owls. :|
Calibration of gas chromatography?
What is the precedure for calibration of gas chromatography? How calibration is perform for gas chromatography? What is the precedure for calibration of gas chromatography? How calibration is perform for gas chromatography?
What is grass chromatography?
There is no such thing as grass chromatography. there is only High Performance Liquid Chromatography, Gas Chomatography, and Paper Chromatography.
What is the name of the method used to separate dyes?
Chromatography is the method used to separate a mixture of dyes or inks.
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.
How is chromatography a analytical tool?
Chromatography is an analytical tool used to separate and analyze complex mixtures. It works based on the principle that different components in a mixture will move at different rates through a stationary phase when subjected to a mobile phase. By analyzing the resulting separation pattern, chromatography can provide valuable information about the composition and identity of the mixture being analyzed.
