<b></i>Abstract :</b><i><p align="justify"> <br /> Multi-component rate model can be developed by simulation on inter-phase mass transfer between mobile phase and stationary phase, inter-particle diffusion, and multi-component isotherm. This research is intended to develop a mathematical model and to study phenomena occurs on general multi-component rate model so it will provide a new alternative for equilibrium theory and theoritical plate model. The model is derived from continuity equation. The model resulted include the one which assumed that cromatography process is isoterm, porous particle in the column is spherical with homogen diameter, iquarance of concentration gradient in radial direction, and that mass film transfer mechanism is used to describe mass transfer between mobile phase and stationer phase. Result of the simulation showed stability variation difference for i-component concentration change at bulk phase for each different amount of column grid. Mean while for infection concentration change did not give significant influence. Concentration distribution of fluid which flow stagnantly into particle pore showed a gauss curve pattern in certain time interval, which in this research is 0.0012 second for its maximum concentration. Furthermore concentration which is absorbed by particle based on langmuir isoterm is higher than concentration penatrated the particle pore. Reviewing order two kinetic, exclusion size effect, and mass transfer effect can do further development of this general multi-component rate model, and flow rate influence. <br />
