Which of the following statement about chromatography is CORRECT? In ion-exchange chromatography, charged substances are separated via column materials that carry a same charge. Using gradient elution in LC can shorten the separation time without sacrificing the resolution of early peaks. In normal-phase chromatography, if the order of solute polarities is A>B>C, then the order of retention time will be C>B>A (i.e. A will be eluted out first). In size-exclusion HPLC, larger molecules will be eluted out slower than smaller molecules.
