Methods for determining the longitudional diffusivities of liquids in flowing beds are discussed. One method is to inject a sudden concentration signal into the fluid at the inlet and to measure the change in the signal with time at the outlet. Another method, which is the main subject of consideration, is tbe frequency response technique method in which a continuous sine wave is introduced at the inlet. Equations are derived and extended for liquids using concentration units, instead of mole fraction units as were used in the basic theory put forth by Rosen and Winsche (Chem. Phys. 18 1587
