Predict the order of elution of the components in this mixture. Assume that the chromatography uses a silica column, and the solvent system is based on cyclohexane, with an increasing proportion of methylene chloride being added as a function of time.arrow_forwardAn LC separation specifies that the mobile phase be 25% tetrahydrofuran (THF) in water. Unfortunately, the laboratory supply of THF is temporarily exhausted. Thus, the mobile phase is made with acetonitrile (CH3CN) instead. What is the ratio of CH3CN/H20 that has the same strength?
