Indoor air quality monitoring applications require both high selectivity and sensitivity, which are difficult to reach with solid state gas sensors. An ultra small packed gas chromatographic column designed for a micro total analyzing system (/spl mu/TAS) based on a solid state gas sensor as a detector and used to determine the concentration of benzene, toluene and xylene (BTX) in indoor and outdoor environments is described. The gas chromatographic approach allows a further selectivity… CONTINUE READING
