Abstract
The major components of manmade aerosols are created by the burning of coal and oil. Aerosols are recognized to significantly impact the climate through their effects on solar and terrestrial radiation. Accurate speciation and measurement of aerosol composition is an important first step in understanding and managing these pollutants. This Phase II proposal continues development of a small, portable, detection system specifically for the collection, speciation and identification of gas phase and aerosolized organics. This Mini Gas Chromatograph collects samples and operates without the need for compressed-bottled gas by using Seacoast's proprietary chemicapacitive sensor array and commercial sensors with a preconcentration/chromatography system, combining selectivity from a diverse sensor array with a miniature sampling system for amplified sensitivity. Specific components are: 1) sample preconcentrator/collector capable of being heated quickly, 2) capillary column to separate the chemicals released from the preconcentrator and provide selectivity, 3) the chemical sensor array containing Seacoast's chemoselective microcapacitors and metal-oxide-based detectors, 4) integrated user interface. In Phase I Seacoast demonstrated that the system is capable of analyzing gas-phase and aerosolized volatile organics. In Phase II we propose to further develop the system's capabilities with a focus on improving sensitivity and collection efficiency.
