These chromatograms were recorded using reverse phase HPLC. a. Give an example of a mobile phase that might be used for this type of separation (i.e. reverse phase). b. Give an example of a detector that might be used for these compounds. c. Give an example of a stationary phase that might be used for these separations. d. Chromatogram B was recorded on the same column and with the same sample as chromatogram A, but the separation is very different. This is because the mobile phase was changed between the two separations. Explain how the mobile phase was changed to affect the separation so dramatically
