Paper chromatography is a technique that involves placing a small dot or line of sample solution onto a strip ofÊchromatography paper.The paper is placed in a container with a shallow layer ofÊsolvent and sealed. As the solvent rises through the paper, it meets the sample mixture, which starts to travel up the paper with the solvent. This paper is made ofÊcellulose, aÊpolar substance, and the compounds within the mixture travel farther if they are non-polar. More polar substances bond with the cellulose paper more quickly, and therefore do not travel as far
