Consider a separation performed on a 30.0 mm long open tubular column with a 0.50 mm diameter and a 2.0 µm thick stationary phase. Compound A eluted at 12.63 min, compound B eluted at 13.24 min, and the unretained solvent eluted at 1.205 min. What are the adjusted retention times, t, and retention factors, k, for compounds A and B? TRA= TRB = 12.035 k = 9.5 KB = 10.0 11.425 What is the separation factor (relative retention), a, for this separation? Incorrect The widths at half-height, w₁/2, of the peaks for compounds A and B are 0.120 min and 0.253 min, respectively. Find the number of theoretical plates, N, and plate height, H, for each compound. NA = NB = HA= HB Incorrect Incorrect Incorrect Incorrect min min mm mm

Consider a separation performed on a 30.0 mm long open tubular column with a 0.50 mm diameter and a 2.0 µm thick stationary phase. Compound A eluted at 12.63 min, compound B eluted at 13.24 min, and the unretained solvent eluted at 1.205 min. What are the adjusted retention times, t, and retention factors, k, for compounds A and B? TRA= TRB = 12.035 k₁ = 9.5 KB = 10.0 What is the separation factor (relative retention), a, for this separation? 11.425 Incorrect The widths at half-height, w₁/2, of the peaks for compounds A and B are 0.120 min and 0.253 min, respectively. Find the number of theoretical plates, N, and plate height, H, for each compound. NA = NB = HA= HB = Incorrect Incorrect Incorrect Incorrect The number of theoretical plates for the column is calculated as N = √√N₁ × NB X Using N₁ and NB, calculate the expected resolution for this separation.
