Step by step
Solved in 2 steps
- In normal-phase HPLC chromatography, the stationary phase is polar and the mobile phase is nonpolar. In the reversed phase we have just the opposite; the stationary phase is nonpolar and the mobile phase is polar. Describe molecules in which move faster or slower in each case.TLC relies on differences in non-covalent forces. Explain the role of these non-covalent interactions in determining the Rf value obtained.A) What are the basic principles underlying TLC technique? B) Draw a TLC plate and explain how TLC can be used to identify the presence of a specific compound in an organic mixture.
- Q2) In the thin layer chromatography experiment, calculate the relative mobility for the two dyes if the distance traveled by the solvent (ethanol) was 3 cm, the distance traveled by the purple dye was 2.5 cm, and 1.5 cm for the red dye? Which dye is considered less soluble in ethanol?how does TLC determine if a sample is pure?What is chiral chromatography?
- A student performs a TLC experiment and at the end of the experiment, sees no spots other than the initial spot. What does this mean, and what should the student do to fix the problem?what chromatography seperation how is tlc part of itExplain why TLC cannot be used for some volatile low molecular weight substances such as toluene.
- Both melting points and TLC rely on differences in non covalent forces. Explain the role of these non-covalent interactions in the final answer obtained (melting point and Rf value).Please propose a chromatography-based strategy to purify human insulin proteins that have been expressed in bacterial cells.Use a suitable model to explain how separation and identification of a mixture of organic compounds can be achieved with a thin layer chromatographic (TLC) technique.
