摘要： A microelectromechanical heating apparatus and fluid preconcentrator device utilizing same wherein heating elements of the apparatus are sized and spaced to substantially uniformly heat a heating chamber within a heater of the apparatus. Tall, thermally-isolated heating elements are fabricated in Si using high aspect ratio etching technology. These tall heating elements have large surface area to provide large adsorbent capacity needed for high efficiency preconcentrators in a micro gas chromatography system (μGC). The tall heating elements are surrounded by air gaps to provide good thermal isolation, which is important for a low power preconcentrator in the μGC system.
