Abstract This paper describes a vapor fortification method for preparing quality assurance/quality control soils for volatile organic compound analysis. Treatment of soils with volatile organic compounds occurs in a closed container in a manner somewhat analogous to the way the vadose zone often becomes contaminated. One advantage of this method for preparing soils for quality assurance/quality control purposes is that the efficiency of various extraction methods can be reliably compared. Furthermore, by substantially reducing the error due to sample inhomogeneity, the error associated with the determinative step can also be properly evaluated.

Micro electro-mechanical system (MEMS) technology is flourishing the development of various sensors. Conventionally MEMS devices have been extensively used for upward performance of gas sensors over a period of time. This paper presents the designing of meander shaped microheater with the commercial FEM tool is used for simulation. Microheater is designed for application of VOC sensing applications. As the volatile organic compounds are to be vaporized a microheater is used. The geometric aspects of the microheater state the temperature effects on the VOC’s.Thus the dimensions were optimized for uniform distribution of heat across the surface. It was observed from the analytical analysis and FEM simulation that at 2um thickness, Microheater was able to distribute the heat uniformity across the surface
