Performance of a Thermally Desorbable Diffusion Sampler for Personal and Indoor Air Monitoring
A DIFFUSION PASSIVE SAMPLER SUITABLE FOR LARGE SCALE INVESTIGATIONS ON POPULATION EXPOSURE TO VOLATILE ORGANIC COMPOUNDS (VOC) IN INDOOR AIR HAS BEEN DESIGNED AND TESTED. THE SAMPLER IS CHEAP, LIGHT AND COLLECTS VOC AT A FLOW OF 4-8 CM3/H OVER ONE WEEK, DEPENDING ON THE COMPOUND. THE SAMPLING FLOW IS NOT INFLUENCED BY AIR HUMIDITY OR AIR VELOCITY. TENAX AND CARBOTRAP HAVE BEEN TESTED AS ADSORBENTS. THE VAPOURS ARE DESORBED THERMALLY AND ANALYSED BY GAS-CHROMATOGRAPHY USING COMMERCIAL INSTRUMENTS. THE SENSITIVITY FOR ONE WEEK EXPOSURE IS ABOUT 1 UG/M3.
