Question
Substances A and B have retention times of 16.40 and 17.63 min, respectively,
on a 30.0-cm column. An unretained species passes through the column in 1.30 min. The peak
widths (at base) for A and B are 1.11 and 1.21 min, respectively. Calculate
(a) the column resolution,
(b) the average number of plates in the column,
(c) the plate height,
(d) the length of column required to achieve a resolution of 1.5.
