Explain why you selected the sample you provided. c. Give an example of a stationary phase that can be used for these separations. Explain why you selected the sample you provided. d. In order to obtain the chromotogram B, what changes should be that can be made in the separation process. 4) Separation was performed using reverse phase HPLC for a mixture of different molecules and the following chromatogram A and then chromatogram B were recorded. Answer the following questions for the reversed-phase HPLC chromatography (for chromotogram A)
