Why must the spot be applied to the TLC plate above the level of development solvent? 6. What will be the result of adding too much sample to the TLC plate?Separation of Amino Acids by Thin Layer Chromatography Lab Questions 7. Why must a pencil be used for drawing the line and spotting? 8. How will the Rf value of a compound be affected if the developing solvent is allowed to run off thetop of the TLC plate (e.g. the TLC plate is allowed to remain in the developing chamber after thesolvent front has reached the top of the plate.)? Explain. Be specific. 9. Describe what an iodine vapor chamber is and explain how does it work? (Hint: Backgroundinformation – showing spots up chemically talks about two methods using Ninhydrin and Iodinecrystals)Separation of Amino Acids by Thin Layer Chromatography Lab Questions 1.
