Computer Aided Simulation of Dispersion Theory Based on Experimental Data by Zone Circulating Flow-Injection Analysis

Abstract

Computer aided simulation of dispersion theory based on the experimental data by zone circulating flow injection analysis (ZCFIA) is described. Using a multi-step peristaltic pump, a set of damped curves were obtained under conditions of laminar flow and various revolution speeds of the pump. By analyzing these curves with computer aided simulation, a great deal of information concerning the dispersion theory were acquired. Quantitative correlations among residence time, flow rate, length and inner diameter of tube, sample volume and dispersion coefficient were obtained by evaluating constants Ks and exponents μ's for each qualitative formulation. Six conclusions suitable for the various conditions involved were obtained. It can be thought that these conclusions play an important role in the FIA theory and experiments.
