Technical principle

Catalytic oxidation method Catalytic oxidation method is the measurement of H2S molecules converted into SO2 molecules under high temperature conditions by a specific catalyst.UV fluorescence is based on molecular emission spectroscopy. SO2 molecules absorb ultraviolet (190nm~230nm) energy to become excited state molecules.Excited molecules are unstable and release excess energy in the form of fluorescent photons when returning to the ground state.
