Abstract
One of the critical factors for a successful scale-up of LC using the rate models is accurate parameter estimation. Three types of parameters are needed to carry out model calculations using the rate models. Isotherm parameters, the particle porosity, and the bed void volume fraction are most important to the accuracy of model calculations. Physical dimensions of the column are also important, but they can be specified or precisely measured. Less important parameters are the mass transfer parameters that usually do not affect the general location of an elution peak. They affect the sharpness of a peak or breakthrough curve. However, such an influence is not extremely sensitive to the minor fluctuations of the mass transfer parameters. Thus, the estimation of these parameters does not have to be very stringent. As always, parameter sensitivity analysis can be carried out using computer simulation by varying a parameter (say 10 %, 20 %, or more) to see the impact on the chromatogram.
