Abstract
In this paper, a hybrid-lattice array of micro post structure was proposed to deal with the velocity fluctuation in the channel of traditional semi-packed micro gas chromatography column. Its flow field was analyzed by using COMSOL software. According to the differences in the six types of microarray structures and the distribution of the flow velocity field of each structure, a triangular-quadrangular hybrid lattice array structure 1 is determined, which can most effectively improve the uniformity of the velocity field. The hybrid-lattice array microstructures proposed in this paper can effectively improve the velocity field distribution in the channel of semi-packed micro gas chromatography column. It provides a theoretical basis for the structural design of new micro gas chromatographic columns.
