Harjit Kaur Che 201 Ex 15 I A . TLC of Analgesic Compounds – The purpose of this experiment was to learn about Thin Layer Chromatography. TLC is a technique used to separate mixtures. It is usually performed on a glass sheet, aluminum foil or silica gel. It is used to find the components of a mixture and it can also be used to detect pesticides in food. After the sample has been applied on the plate, a solvent or solvent mixture is drawn up the plate via capillary action . Because different compounds ascend the TLC plate at different rates, separation is achieved. II A. For this experiment we did Part B, a developing solution of ethyl acetate: acetic acid 200:1 is used. A filter paper is then added the solution to help ascend the mixture throughout the beaker. We then got 3 samples, Aspirin, Acetaminophen, Caffeine and unknown sample A. A line was drawn on the 1 cm mark and the different solutions were then drawn up and added to the TLC plate. The spotted TLC plate is then added to the developing solution. After the solvent moved past the ¾ line it is then
