Gel permeation chromatography and liquid Chromatography are used for analyzing various epoxy resins. The chromatograms are compared with related information available from each. Because the separation is based on different principles, each method gives unique and different information about the same sample. For a complete analysis of epoxy resins, both techniques seem to be required.

Students develop presentations regarding separation techniques and participate in discussions focussed on the contents, organization, and indexing of a "self-sharpening" card file on separations.
