LABORATORY TESTING OF AN INEXPENSIVE PASSIVE SAMPLER WITH THERMAL DESORPTION FOR VOLATILE ORGANIC COMPOUNDS IN INDOOR AIR
The features of a small (160x6 mm) inexpensive diffusion sampler employing Tenax as adsorbent to be used in indoor air quality investigations have been studied in a glass test cell with vapours of benzene, toluene, hexanal, 1.3-xylene, n-decane, limonene and naphtalene. Mean sampling flows over one week of 5.2-7.6 cm**3/h have been observed, independently of air humidity (40-80% R.H.) and air velocity (down to 0.001 m/sec.). The tightness of different cap types was determined employing perfluorocarbons as tracers and in few cases found as low as 0.1 cm**3/week. The sampler is amenable to completely automatic analysis.
