A column has a length of 30.0 cm. The unretained species passes through the column in 1.30 min. A and B are eluted at 16.40 and 17.63 min with the peak width (at base) of 1.11 and 1.21 min, respectively. Calculate the followings: (a) average number of theoretical plates in the column (b) plate height (c) column resolution for peaks A and B (d) number of plates to achieve resolution (e) length of column required for (d) (f) time required to elute B with the column of (e) 1.5
