Sulfur Analyzer

(Determination of Total Sulfur in Petroleum and Petroleum Products by Oxidative Combustion and Ultraviolet Fluorescence Method)

INTRODUCTION:

Injected into quartz tube and mixed with O₂, the sample burns. S is converted into SO₂. Then the combustion gases are routed through a membrane drying system to remove all water. SO₂ is exposed to UV light to form SO₂ *. As the excited SO₂ relaxes, photons are emitted at a specific wavelength range and detected by a photomultiplier tube (PMT). The amount of light detected is proportional to the amount of sulfur.
