Construction of an automated, sequential air sampler for remote monitoring of organic atmospheric pollutants
Technical Report
·
OSTI ID:5182038
An automated, low-volume air sampler has been constructed for monitoring organic atmospheric pollutants at remote sampling locations. The sampler is designed to operate unattended and requires a single battery charge for up to a month, while sixteen sample tubes charged with an appropriate adsorbent are sequentially exposed. The design includes optimization of components such that the sample cartridges, flow rate, absorbent particle size and mass, and absorbent characteristics facilitate qualitative and quantitative analyses. Of the adsorbents most frequently used for air sampling, Florisil was selected because it has a high collection efficiency and because it is amenable to rapid and simple analysis. A multiposition valve allows isolation of the adsorbent in each sample tube both before and after sample collection to preserve sample integrity. 37 refs., 6 figs., 5 tabs.
