問題詳情

10. Which of the following statements about the elution process of LC is not true?
(A) In nornal-phase LC, the least polar analyte is eluted first because it is the most solublein the mobile phase.
(B) In normal-phase LC, a less polar solvent has higher eluent strength.
(C) Increasing the polarity of the mobile phase has the effect of decreasing the elution timein normal-phase LC.
(D) In reversed-phase LC, a more polar solvent has lower eluent strength.
(E) In reversed-phase LC, increasing the mobile phase polarity increases the elution time ofthe less polar analyte.
