ABSTRACT:
A thin bed sorption/desorption apparatus includes a heater element laminated within a high temperature chemically inert polymer with an adhesive on the outside of the laminate being used to attach a thin film of small particle size sorptive material. Various embodiments of the apparatus are each arranged to provide a flow of a sample to be analyzed across the surface of the sorptive material. The method for making the thin bed sorption/desorption apparatus includes the steps of encapsulating a thin-film heater element in a laminated structure of a polyimide which is a high temperature, chemically inert polymer. The outside surface of the laminate is coated with a polyimide adhesive which is diluted with dimethyl formamide. The sorptive material in the form of a powder having a maximum particle size of 100 mesh is applied to the wet adhesive. Subsequently, the coated structure is heat cured at approximately 220.degree. C. for a period of approximately 30 minutes until the adhesive is dry and the sorptive material layer is fixed to the laminate.
