Current Research: Chilled liquid (e.g. tetraethylene glycol dimethyl ether) has been used to scrub a variety of organic compounds from gas streams. The chilled tetraglyme traps volatile organic compounds (VOCs) as the gas stream is bubbled through it. The VOCs in the tetraglyme are dispersed in water, which is analyzed by purge-and-trap followed by GC/MS (Gas Chromatographic/Mass Spectrometry). This method has been used for the determination of VOCs in ambient air. Various VOCs including benzene, chlorobenzene, ehtylbenzene, toluene, and naphthalene were identified. How can liquid traps be integrated with microfluidic system for the determination of volatile organic compounds in ambient air in real time? My current research investigates the possible integration of liquid trap and microfluidic to produce a concept machine for real time determination of VOCs in ambient air.
