Isolation of Three Components from Spearmint Oil: An Exercise in Column and Thin-Layer Chromatography  Don R. Davies and Todd M. Johnson
In this exercise, the three major components of spearmint oil, (+)-limonene, L-(-)-carvone, and (1R,2R,4R)-dihydrocarveol, are separated by silica gel column chromatography. The separation is monitored by thin-layer chromatography, and IR analysis is employed to verify the identity of the separated components.

Floating Squares (GCMP)  David M. Whisnant
Floating Squares: this is a resource in the collection "General Chemistry Multimedia Problems". In this problem we will coat a piece of notecard with graphite (from pencil lead). We then will float the piece in two beakers containing water and a second solvent. General Chemistry Multimedia Problems ask students questions about experiments they see presented using videos and images. The questions asked apply concepts from different parts of an introductory course, encouraging students to decompartmentalize the material.
