It is an inexpensive method of separating dissolved chemical substances by their different migration rates across the sheets of paper. <\/p>\n\n\n\n<p>The compounds in the mixture separate themselves based on the differences in their affinity towards stationary and mobile phase solvents under the capillary action of pores in the paper.
