The general elution problem in chromatographic experiments is to (i) adequately separate closely eluting species from each other, and (ii) to elute all species in the sample in a timely manner. How could you improve the separation illustrated below for each case. (Don't only give a "key word". Briefly describe what you would do and why it might work. There may be more than one experimental change that would improve the separation. a) a gas chromatographic experiment? b) a liquid chromatographic experiment? c) a thin layer chromatographic experiment?
