How to Use Chromatography as a Science Teaching Aid.
Ganis, Frank M.
Presented are five procedures which permit the effective teaching of chromatography with equipment which is readily available, economical, and simple in design. The first procedure involves a study of solute partition in two immiscible solvents and of countercurrent distribution. The second illustrates the use of unidimensional ascending paper chromatography in separating the same mixture of colored components used in the first procedure. The third procedure illustrates the separation of three common sugars by unidimensional ascending paper chromatography. The fourth procedure demonstrates the separation of amino acids by ascending two-dimensional paper chromatography. The fifth procedure involves the separation of a dye mixture using thin-layer chromatography. (DS)
