  • Methods of Measuring and Monitoring Atmospheric Sulfur Dioxide

    Nevertheless, if trends over a number of years are considered, for example, by a comparison of one 5-year average with the next or of 5-year running averages, the variation due to wind, weather, etc., tends to become small and the measurement of SO2 more precise; the 5-year average has long been recommended by the DSIR for this purpose.

    Measurement results showed that the BrO mixing ratio could reach up to 30 ppt in the Arctic and 10 ppt in the marine boundary layer (Platt and Hönninger, 2003; Martin et al., 2009). BrO in the free troposphere at the global scale was estimated to be at a level of 0.5–2 ppt based on spaceborne, ground-based, and sounding measurements with the

  • Non-dispersive UV Absorption Spectroscopy: A Promising New

    A new type of instrument for in-situ detection of volcanic sulfur dioxide is presented on the basis of non-dispersive UV absorption spectroscopy. It is a promising alternative to presently used compact and low-cost SO2 monitoring techniques, over which it has a series of advantages, including an inherent calibration, fast response times (in-situ instruments.

  • Development of a Novel Porous Membrane Denuder for SO2

    2021-2-15ABSTRACTConventional denuders made of glass or metal are too heavy and bulky to be used in personal sampling systems. In this study, a portable Porous Membrane Denuder (PMD) was developed for personal sampling. The PMD utilizes the porosity of the membrane material and a configuration of multiple parallel flow channels to reduce the size and weight of the device, while

This study demonstrates the great potential of this new type of denuder for many applications in the field of environmental and industrial hygiene monitoring. Particle loss fractions of the four types of PMDs in the size range of 1 to 10 μm were also measured and were 2.9%, 5.2%, 5.7% and 7.3%, respectively.
