Substances A and B have retention times of 18.40 and 20 min, respectively, on a 30 cm column. An unretained species passes through the column in 2.40 min. The peak widths (at base) for A and B are 1.01 and 1.10 min, respectively. Calculate: (a) The column resolution Answer (b) The average number of plates in the column Answer (c) The plate height Answer
