Low Pressure Drop Micro Preconcentrators With a Cobweb Tenax-ta Film

Year: 2010

Type: conference-paper

Abstract: This paper reports the design, simulation, and experimental evaluation of high performance low pressure drop (<100Pa/cm) micropreconcentrator (µPC) chips (7mm 7mm 0.38mm) for micro total analytical systems.The µPC's high performance is attributed to the multiple inlets/outlets, novel high-aspect-ratio (380 m) parabolic reflectors, and cobweb configuration of adsorbent films all in which promote the adsorption of chemical species.Flow pattern simulations were used to verify the underlying concept of the design.The adsorption capacity of hydrocarbons was used to evaluate the µPCs experimentally.The performance of the new design was found to be more than 2 orders of magnitude higher than the first generation reported previously. 0-9640024-8-5/HH2010/$25©2010TRF
