A chromatographic peak has a retention time of 120 s. the width at the base of the peak equals 3.2s, at the intersection of the sides of the peak with the baseline. If the column is 200 cm long. a.What is the number of theoretical plates. b. The equivalent height of each plate. c. The sensitivity of the method if the retention time of the mobile phase is 50 s.
