| Abstract | BIOSIS COPYRIGHT: BIOL ABS. Some data on a newly developed filter/sorbent indoor air SVOC sampling device for thermal desorption analysis are described. Thermal desorption of SVOCs spiked on Tenax had response factors identical to on-column injection except for highly polar compounds like fatty acids. SVOCs spiked on quartz fiber filters had for non-oxygen compounds). Low nanogram on-tube amounts of lower desorption efficiency. In addition, it was indicated that the "memory" effect was an important source of background contaminations that might impair analysis of low nanogram on-tube amounts of some SVOCs. Polar SVOCs in the gas phase appear to adsorb to the quartz fiber filters. This functions as a precleaning of the sample and thus minimizes the problem with coeluting peaks. The relative standard deviations of air concentrations of 10 SVOCs in an office estimated from nine duplicate samples appeared to be sufficiently low to distinguish a day to day variation. |
