Problem 22-39

(a) The asymmetric chromatogram in Figure 22-14 has a retention time equal to 15 min, and the values of A and B are 33 and 11 s, respectively. Find the number of theoretical plates. (b) The width of the Gaussian peak in Figure 22-9 at a height equal to 1/10 of the peak height is 4.297. Suppose that the peak in part (a) is symmetric with A B 22 s. Use Equations 22-28 and 22-29 to find the plate number. 2
