Experiments on Paper Chromatography | Botany

The below mentioned article includes a list of three experiments on paper chromatography. 1. Experiment to separate amino acids in a mixture by paper strip chromatography: Principle: It is based on the fact that paper chromato­graphy separates compounds on the basis of their different rates of migration of filter paper (cellulose). The rates of migration depend upon the solvent which [...]
