Modelling of a GC based Pre-Concentrator Covering Material for SAW E-Nose Gas Sensor


This paper presents a modelling cum flexibility study to aid in the development of a Gas Chromatograph (GC) based pre-concentrator technology for Surface Acoustic Wave (SAW) sensor applications. Finite Element Method is computationally adopted and implemented via commercially available software COMSOLMultiphysics. A pre-concentrator device has been modelled, simulated with different covering materials and studied by cyclic micro heating and cooling of the Nichrome heating element for the purpose of device temperature stability. A temperature profile for two materials (Teflon with Aluminum and Teflon without Aluminum) as covering material of pre-concentrator is studied and the conclusions from such a study are reported.
