using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done on a plate that is coated with a layer of absorbent

Thin-Layer Chromatography of Analgesics Abstract: In this experiment thin-layer chromatography (TLC) was used to determine the composition of an unknown mixture of analgesics given five references of AC‚ ASP‚ CAF‚ IBU‚ SAL‚ an unknown consisting of a mixture of three of the references‚ and two unknowns (6‚23) containing a single reference compound. The composition of the unknown mixture and two single unknowns were determined by spotting the reference compounds and the unknown compounds on two
