- Whagt is the purpose of the following? Separate the active ingredients in an unknown over the counter analgesic using TLC (thin layer chromatography). Make a preliminary identification of each active ingredient in an unknown tablet by comparing its Rf value(s) with the Rf values of four different known active ingredients:Upon screening with TLC (made of silica gel) chromatography using hexane/chloroform (3:1) as eluting solution, 3 spots were detected corresponding to a (A) polyphenol, a (B) tannin and an (C) alkaloid. Write the letters of your answers on the spots in the chromatogram shown at the right.Upon screening with TLC (made of silica gel) chromatography using hexane/chloroform (3:1) as eluting solution, 3 spotswere detected corresponding to a (A) polyphenol, a (B) tannin and an (C) alkaloid. Write the letters of the answer onthe spots in the chromatogram shown at the picture.

- If I am doing an experiment on human H295R cells where I would treat the with very low concentrations of both Atrazine and DMSO. I have the cell culture media and the DMSO but I need to make a (9ppm Atrazine, DMSO) by dissolving powdered atrazine in DMSO. 1. If I have 0.04 g of Atrazine left in the bottle, how much (9ppm Atrazine, DMSO) solution can Imake? 2. How much atrazine stock willl I need to make 15.5ml of treatment solution (3ppb ATZ, cell culture media)? 3. What would be best for me to meausre the stock ATZ and what would be best for me to measure the cell culture media? 4. And then how much DMSO would I need to add to my 15.5 ml control solution?2.
