Why on analysis with Gas chromatography was carried out in stages derivatization?
Step by step
Solved in 3 steps with 2 images
- How can you ensure that your column chromatography will give you a higer yield?Compound A has a lower affinity for the stationary phase thancompound B and can dissolve well in the mobile phase. In theseparation of the mixture of A and B by column chromatography,which compound will be eluted first from the column? ExplainThe following questions relate to the column chromatography experiment.a. Why does the fluorene elute first from the column?b. Why was the solvent changed in the middle of the column procedure?
- Describe briefly, but precisely, what you would have done in order to get to this stage. You can assume that you have been given a suitable thin layer chromatography plate.Describe in detail the function of column in gas chromatography system.Please Explain clearly Why couldn’t you use acid-base extraction to separate a ketone and an alcohol? why do we use column chromatography instead? Please explain clearly the benefits of both methods and why is one method preferred over the other.
- What is the other term for mobile phase in chromatography? (Eluant, Eluate, or Solvent)Write short notes on molecular exclusion chromatography with representative picture.thin layer chromatography What would happen to it if you decreased the polarity of the mobile phase? Explain. Please help me this question! Thank you a lot
- If I were trying to separate two compounds that eluted closely together. How would theirseparation be affected if I accidentally performed my column chromatography with a crookedcolumn?In a column chromatography experiment. After purifying compounds by column chromatography, what are two other methods that you can use to confirm the identity of the compounds in each fraction? (other than TLC!) make sure to explain aswell. Thank youWhy was it important that you marked the origin line and component locations on the paper chromatography with a pencil, and not a pen or marker?
