Year: 2008
Type: conference-paper
Abstract: The design, simulation, fabrication and testing of a thermally desorbed micro preconcentrator (µ-TPC) is presented.The device consists of multiple inlets/outlets with novel high-aspect-ratio (240µm) crisscross µ-pillar structures and on-chip thermal desorption capability.The µ-TPC has a total inner surface area of 200 mm 2 and a total inner volume of 6.5 µL resulting in a surface to volume ratio of 31 mm -1 .The 3-D structures were coated with Tenax TA based on polymer inkjet printing methods.The 7 mm × 7 mm µ-TPC was capable of collecting volatile organic compounds (VOCs) with a preconcentration factor > 1000.
