Solvent volume per cm of column = 0.15*3.14*(0.30 cm/2) 2 = 0.0106 mL/cm Linear flow rate = (0.20 mL/min)/(0.0106 mL/cm) = 19 cm/min 11. 0.6 and 6 12. 3.59 and 4.69 13. 603 and 0.854 14. (a) Column 1 (b) Column 2 (c) Column 1 (d) same (e) and (f) compound B 15. The linear flow rate at which solution goes past the stationary phase determines how completely the equilibrium between the two phases is established. This determines the size of the mass transfer term (C x ) in the van Deemter equation. The extent of longitudinal diffusion depends on the time spent on the column, which is inversely proportional to linear flow rate. 16. (a) 0.1 mm 17. Diffusion constants in gases are 10 4 times greater than those in liquids. 18. (a) 112 (b) 0.89 mm...
