Study of the separation processes of gases in the microchannel based on the stochastic simulation

Abstract

Abstract One of the main problems in the development of microfluidic gas chromatography columns is the complexity of the preliminary modelling of the microfluidic systems, namely, the complex modelling of physicochemical processes on the inner surface of the microchannel walls and the simulation of carrier gas movement. The purpose of this work is to develop an integrated computer model for the separation of sample gas components in a gas chromatographic column that takes into account the effect of the carrier gas on the gas- sample particles and adsorption processes in the surface layer. The proposed model is based on stochastic method. The simulation results can be used to improve the development of microfluidic gas chromatography columns and other devices in which the separation of gas mixtures occurs.
