Institution:Towson University EPA Project Officer: Hahn, Intaek Project Period: October 15, 1996 through October 14, 1999 Project Amount: $333,141 RFA: Analytical and Monitoring Methods (1996)RFA Text | Recipients Lists Research Category:Air Quality and Air Toxics ,Environmental Statistics ,Water ,Land and Waste Management ,Air ,Ecological Indicators/Assessment/Restoration Description: Ion and liquid chromatography are two of the most widely used techniques inenvironmental analysis. Both remain relegated to the laboratory due to the lackof truly portable and robust equipment. Based on a considerable amount ofpreliminary work, we propose here the development of briefcase sized packedcapillary and open tubular ion/liquid chromatographic instrumentation of weightunder 20 lb. All operation control and data acquisition will be carried out by alaptop personal computer. The instrument will be capable of operating off ACpower, or for 8h from four flatpack NiMH batteries. Both suppressedconductometric and optical detectors will be developed. These instruments willoperate at single digit µL/min flow rates, using very little consumables andgenerating very little waste. Chromatographic efficiencies will equal or exceedthose of present day conventional size benchtop instruments. Two completesystems will be built. These chromatographs will be coupled to wetted denuders (for the collectionof soluble ionogenic gases) and bead packed wetted coils (for the collection ofaerosols) to devise a new generation of near-continuous gas/aerosol analysisinstrumentation that are expected to be not only far more compact but alsosubstantially more sensitive (sub-ppt for most gases, pg/m3 for most aerosolconstituents) than their previous counterparts. These will be field tested byourselves and also in collaboration with the National Center for AtmosphericResearch. (NCAR). The inexpensive syringe pump driven gradient LC system will be field tested for pesticide analysis in runoffs from local cotton fields.
