Chromatography has been a very potent tool of research for the past five decades. Within the framework of the existing curriculum, it lends itself to being a strong instructional technique. It demonstrates, for example, how one  may determine the composition of complex mixtures found in nature. Controls and unknowns are employed throughout the experiment in a manner similar to that used  in basic research. Experiments which may be done with this kit:    Separation of dyes found in ink.  Separation of amino acids in a mixture.  Separation of pigments found in plants.  Separation of amino acids in fruit juice.  Separation of amino acids and peptides on a fingerprint. Separation of table sugar (sucrose).
