Abstract
The goal of this project was to develop and carry out methods for evaluating a variety of Tenax-coated micro-preconcentrators and fused-silica solid phase micro-extraction (SPME) fibers for applications in micro-electro mechanical systems based gas chromatography. In the past, micro-preconcentration devices and SPME fibers have been fabricated and applied to gas chromatography (GC) systems. However, most of the preconcentration devices that utilized Tenax involved a packed form of the adsorbent polymer instead of the thin film surface coating and newly developed cobweb styles used in this project. Additionally, SPME fibers with Tenax as a sorbent were also of a new design and had not been extensively evaluated. Although time limitations prevented the extensive study of preconcentrators and SPME fibers, this project did suggest that the Tenax-based devices could feasibly be applied to micro-GC systems. Moreover, the methods developed in this project could be used for more extensive systematic evaluation in the future.
