- The darkroom system adopts the latest foreign technology, and the key components adopt imported detection components, which improves the detection accuracy of the instrument
- The instrument adopts imported membrane dryers to absorb moisture, saving the trouble of replacing magnesium perchlorate frequently, and reducing the problem of air leakage.
- The use of computer control temperature improves the instrument temperature control precision, and not easy to overtemperature.
- The use of air cooling instead of water cooling, save water resources.
- You can take the existing calibration curve with standard sample calibration for sample analysis
Working Principle of TT-UVS900 Ultraviolet Sulfur Analyzer
- A measured sample is introduced into a high-temperature cracking furnace (~1000 °C), where it undergoes complete combustion and oxidation. Sulfur compounds present are quantitatively converted into sulfur dioxide (SO₂). The reaction gas, carried by an inert carrier gas, passes through a membrane dryer to remove moisture before entering the reaction chamber.
- Inside the chamber, SO₂ molecules are irradiated by ultraviolet light at specific wavelengths, exciting their electrons to higher energy states. As these electrons return to their original energy levels, they emit characteristic fluorescence specific to sulfur. This light is detected by a photomultiplier tube, amplified, and converted into an electrical signal proportional to the sulfur concentration. The instrument’s software processes this data to calculate the total sulfur content in the sample.
