SO₂ Data Sheet    

Sulfur dioxide is noticeable component in the atmosphere as well as a major air pollutant. Exceeding a certain concentration, the gas has a significant impact upon human health, the habitat suitability for plants as well as for animal life. Emissions of SO₂ are a precursor to acid rain and atmospheric particulates.

SO₂ sampling

The passive sampler is based on the principle of diffusion of SO₂ molecules onto the absorbent made out of potassium carbonate and glycerin. The quantification is done by ion-chromatography. The samplers are composed of a polypropylene housing with an opening of 20 mm in diameter. To exclude wind and weather disturbances, a glass fiber membrane supported by a wire net is attached and set up in a specially designed protective suspension device.
