(8) Calculate the number of theoretical plates required to achieve baseline separation (Rs = 1.5) for an α
(= k 1 /k 2 ) value of 1.10 in
(a) a packed column where k 2 = 50(b) a packed column where k 2 = 5(c) a capillary column where k 2 = 2(d) a capillary column where k 2 = 0.5(e) as (b) but for α = 1.2.(9) The following values for plate height and gas velocity were obtained for n-hexane on a 2-metre
