Design and Simulation of a Microfabricated Gas Chromatographic Column

This paper describes the development of new micro gas chromatographic column designs intended to optimize the analysis by improving homogeneity of analyte molecules as they progress along the column length. We are particularly interested in applying these approaches for trace analysis of illicit materials such as explosives and other hazardous chemicals. A significant component of this work has been in using computational fluid dynamic (CFD) modeling as a tool to help in optimization of the GC column design.
