Experimenting with various separation techniques (e.g. electrophoresis)

Most organic materials found in nature, extracted from plants or from other live organisms are not pure. Instead, they are a mixture of two or more organic substances. In order to identify each organic substance we first need to separate them and get pure samples of each substance. We can then use other techniques to identify each substance based on it's chemical and physical properties. 
Depending on the type of chemicals, different methods may be used for separation. Among these methods are: Chromatography, electrophoresis, crystallization, filtration and others. Electrophoresis is the method used to separate chemicals using electricity.
 Project description:
In this project you will experiment and try to improve one of the electrophoresis separation techniques. Some material needed for your experiment needs to be purchased. An estimated budget of $40 is required.
