Question 1: (column chromatography) a. What effect on the chromatographic separation is expected if solvent level is below the adsorbent? b. Once the chromatographic column was prepared, why was it important to allow the level of the liquid in the column to drop to the level of the stationary phase before applying the solution of the compounds to be separated? c. Name two methods of carrying out the column chromatography technique? d. What are the two methods of packing a...

What do you understand by theoretical plate in chromatography.? To improve a chromatographic separation should you (i) increase the height of the theoretical plates on the column or (ii) increase the number of theoretical plates on the column. Why?
How can you improve the resolution between two closely spaced peaks in gas chromatography. Describe the process you would undertake to improve separation.
