Excellent work! What is chromatography, its types, paper chromatography, principle, requirements, procedure or method, its advantages over other chromatographies, limitations, applications of Please reconfirm the principle as i have heard the principle is not coz of the water.

Its due to difference in the affinity of the componenet between the stationary phase and mobile phase. Amino acids are zwitter ions i. So amino acids separation rate varies based on pH of mobile phase used.

They are polar compounds so best mobile phases used are polar solvents like propanol, butanol and you may make their pH to basic by adding aqueous ammonia.. For more details do refer books on experimental organic, biochemical or phytochemistry with standard protocols for separation of set of amino acids by paper chromatography. Marine Biology. Electrical Engineering. Computer Science. Medical Science. Writing Tutorials.

Uses and Applications of Paper Chromatography Paper chromatography is specially used for the separation of a mixture having polar and non-polar compounds.

For separation of amino acids. It is used to determine organic compounds, biochemicals in urine, etc. In the pharma sector, it is used for the determination of hormones, drugs, etc. For example, pen inks are often made up of different colours.

The different bonding properties of each molecule type is exploited. Chromatography is used in both qualitative and quantitative analysis of both organic and inorganic samples. This technique uses two types of substances:. It is necessary for the different chemicals in the solution fo have different properties such as molecule size or a different ability to dissolve in a solvent.

The stationary phase will absorb or slow down different components of the tested solution to different degrees creating layers as the components of the solution are separated. Chromatography was invented by the Russian botanist, Mikhail Tsvet.

Chemists use this process to identify unknown substances by separating them into the different molecules that make them up. Six numbered strips of paper towelling with the marker colours noted. Tape the strips to a dowel. Grey; 2. Dark Green; 3. Orange; 4. Dark purple; 5. Brown; 6. Ink is a solution containing a number of different molecules.

These different molecules have different characteristics such as size and solubility. Solubility is a molecule's ability to dissolve in a particular solvent such as alcohol, water or nail polish remover. Because of their different characteristics, each molecule travels at a different speed when pulled along the piece of paper towelling by the solvent.

The lightest particles, which are not necessarily the lightest coloured particles, move more quickly and a greater distance than the heavier particles. Thus, all of the pigments that make up an ink sample are separated out. This chromagraph of black ink used rubbing alcohol as a solvent. Comparing a chromatogram made with the same solid medium and solvent, a comparison can be made to determine the type and brand of ink used at a crime scene.

Uses of Paper Chromatography. Tutor Vista. Thanks I am doing an experiment for science fair with my partner and we chose paper chromatography! Anx a lot but what is another type of chromatography and how to define the changes of liquids on the chromatography. I need a answer to this question without the experiment stuff What is chromatography when it come to dying materials.

Thanks so much for posting this article Teresa Coppens, I am doing a research paper and this has helped me so much. I have cited this site for my research paper, I have checked other rescources and site, of all of them yours is the most helpful and easy to understand. I also successfully completed the experiment.
