試題詳解

11. A gas chromatographic column was used to separate a pair of compounds. The retention times for these two compounds were 11.56 minutes and 11.71 minutes respectively. If the dead time for mobile phase was 1.60 minutes and the theoretic plate height (HETP) was 0.28 mm under the separation condition, what is the column length (in meter) and peak width (in seconds) for these compounds should be when they need to be just totally resolved? Give the equation:
(A) ~80 m and ~6 s.
(B) ~70 m and ~8 s.
(C) ~50 m and ~7 s.
(D) ~60 m and ~6 s.
(E) ~50 m and ~8.0 s.
