Based on the given chromatograph, answer the following questions:
1) Which of the diet sodas have the highest concentration of caffeine? Which standard best reflects this concentration?
2) Which of the diet sodas have the lowest concentration of aspartame? Which standard best reflects this concentration?
3) What is the approximate retention time of benzoate?
4) If the classification of the chromatography run is a reverse-phase chromatography, discuss the relative polarities of caffeine, aspartame and benzoate.
5) Given the data of the diet sodas, which one would you recommend to be the healthiest? (You may need to research the functions of caffeine, aspartame and benzoate. Please add references if necessary.)
