Highly sensitive so2 detection system catalogue

Jun 05, 2020 · A highly sensitive detection system for sulfur dioxide (SO 2) and nitric oxide (NO) was developed via deep ultraviolet differential optical absorption spectroscopy (DUV-DOAS). The wavelength range of 200–230 nm was used which was rarely used before as result of severe cross sensitivity to SO 2 and NO, in this work, this problem was overcame.

  • Sulfur Dioxide Gas Detectors | SO2 Detectors | Industrial

    Sulfur dioxide is a highly toxic gas which poisons its victims via inhalation through the lungs. SO2 combines with water to form sulfuric acid (H2SO4). It is for this reason that sulfur dioxide can burn the respiratory tract upon inhalation. High doses of sulfur dioxide can cause death quite rapidly.
