- Abstract
The design and construction details of an annular diffusion scrubber to be used as a quantitative gas sampler are described. A large-diameter inner tube (12 mm o.d.) wrapped with liquid channel interior of thin membrane (70 µm thickness) provided high collection efficiency. With SO2 as the test gas, the performance data for a high-efficiency annular diffusion scrubber, coupled to an ion chromatograph, are presented. Quantitative collection and excellent reproducibility are observed at air sampling rates up to 2 L/min. The estimated detection limit is 4 pptv for a 20-L air sampling volume.
