To clarify the interrelations between the origin of SBS and VOC, it is necessary to measure instantaneous concentration of VOC, when an illness derived from SBS breaks out. In this study, we developed a direct-reading instrument that can observe the concentration of TVOC continuously using semiconductor gas sensor. The investigation results of sensing property indicates that the instrument exhibits high sensitivity to aromatic hydrocarbons such as toluene and xylene (sufficient sensitivity to detect 30 μg/m3), and very low sensitivity to lower paraffinic hydrocarbons such as Methane and Propane. In additionally, output concentration of this monitor also exhibited a good correlative to TVOC concentration, measured by GC/MS. It means that this monitor can be used for personal exposure measurement and other real time monitoring of TVOC.
