Abstract
Two key challenges to portable gas chromatography are reducing preconcentrator power consumption and accurate temperature control of adsorbent. This paper presents the results of thermal modeling performed to optimize a microfabricated preconcentrator based on a silicon microhotplate and utilizing Metal Organic Framework (MOF) adsorbents. From this modeling, two design changes are presented that reduce the power consumption by 1.5 W and reduce temperature variation across the microhotplate by 50%.
