126. Solving a chemistry problem

34. The chromatogram shows peaks at 0.56 min (unretained component H), at 9.45 min (component B) and at 10.15 min (component D). The width of the peaks of components B and D corresponds to 0.53 and 0.65 min, respectively. The column length is 30.0 cm, the volume of the stationary phase is 13.4 ml, the mobile phase is 18.1 ml. Calculate: a) the number of theoretical plates of the column for components B and D; b) the height equivalent to the theoretical plate for components B and D; c) retention, capacity and distribution coefficient for Bi G components; e) coefficient of selectivity and resolution of the peaks of components B and D. Draw an approximate chromatogram.
