What is TLC Analysis of Over-the-Counter Analgesics about?

This lab analyzes common over-the-counter analgesics using thin-layer chromatography. Students will pulverize samples of Excedrin, Tylenol, aspirin, ibuprofen, and an unknown, then spot the samples on TLC plates. The plates will be developed in different solvent systems and viewed under UV light to observe separated components. Rf values will be calculated to identify the components in each analgesic based on their mobility. Safety precautions will be followed for handling laboratory chemicals.
