Abstract:

A mathematical model for fitting the experimental ICM (integrated conductimetric method) curves developed by the authors in a previous work, is presented for the first time in this study. The proposed model fits the experimental curves with great precision and allows to predict physical dispersion for single-line flow injection system. The correlation of the model's parameters with typical reactionless FIA peak parameters is also assessed. The IDQ coefficient-a novel dispersion estimator previously reported by the authors-can also be predicted when operational FIA variables are changed. Experimental and modelled profiles are compared as a function of the system's variables, showing an excellent agreement. © 2002 Elsevier Science B.V. All rights reserved.
