    在一液相色谱柱上,组分A和组分B的K分别为18和24,柱的固定相体积为1.5 mL,流动相体积为3.0 mL,流速为1.0 mL/min。求A、B的保留时间和保留体积。
    A: tR(A)=30.0, tR(B)=39.0; V(A)=30.0, V(B)=39.0;
    B: tR(A)=20.0, tR(B)=25.0; V(A)=20.0, V(B)=25.0;
    C: tR(A)=18.0, tR(B)=21.0; V(A)=18.0, V(B)=21.0;
    D: tR(A)=21.0, tR(B)=27.0; V(A)=21.0, V(B)=27.0;
    E: tR(A)=30.0, tR(B)=39.0; V(A)=15.0, V(B)=18.5;
