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%.

AbstractA new Cu(II) metal-organic framework, [Cu(L)(OBA)·H2O]n (1) [H2OBA = 4,4′-oxybis(benzoic acid), L = 3,5-di(1H-benzimidazol-1-yl)pyridine] was hydrothermally synthesized and characterized through IR spectroscopy, elemental and thermal analysis and single-crystal X-ray diffraction. Complex 1 is a four-connected uni-nodal 2D net with a (44·62) topology which shows an emission centered at λ ∼393 nm upon excitation at λ = 245 nm. Moreover, complex 1 possesses high photocatalytic activities for the decomposition of Rhodamine B (RhB) under UV light irradiation.
