Paper Abstract

Characterizing indoor air quality requires instrumentation with certain capabilities. Most importantly, indoor air analyzers must be capable of measuring low concentrations of airborne pollutants in complex environments. This capability and many others important to indoor air monitoring applications have been realized in a transportable extractive FT-IR gas analyzer that has recently become commercially available. Feasibility studies have been performed at a variety of sites to evaluate the potential of this new cell-based analyzer for indoor air quality analysis. This paper describes the instrumentation and methodology used to perform these studies and then presents the results of the studies. Through these results, certain conclusions become apparent concerning the instrumental performance features that are required to produce truly useful indoor air quality information.
