Abstract The purpose of this experiment is to use thin layer chromatography techniques to determine the components of an unknown analgesic. One trial was carried out, in which retention factors were determined for aspirin, acetaminophen, ibuprofen, and caffeine. These values were compared to the TLC results of the unknown substance. All values were comparable to the literature retention factors for these substances and the unknown substance was found to contain aspirin, acetaminophen, and caffeine. Ibuprofen was not present on either the determining TLC trial or in the unknown substance. This may be due to the use of improper TLC techniques, and more trials are necessary to determine the true components of the unknown substance. Introduction The purpose of this experiment is to carry out a proper thin layer chromatography procedure, while obtaining experimental retention factors for aspirin, acetaminophen, ibuprofen, and caffeine, as well as to determine the composition of an unknown substance. The retention factor of a substance defined as the distance traveled by the compound
