KEA-6000 sulfur and nitrogen element analyzer
The KEA-6000 sulfur and nitrogen element analyzer uses the principle of ultraviolet fluorescence to measure sulfur. The sample undergoes high-temperature oxidation reaction, and the sulfides in it are quantitatively converted into SO2. The sample gas is dehydrated by a membrane dryer and enters the reaction chamber. SO2 is irradiated with ultraviolet light to produce a specific wavelength spectrum, which is detected and received by a photomultiplier tube. The emitted fluorescence intensity is directly proportional to the sulfur content in the original sample. After microcurrent amplification and computer data processing, it can be converted into an electrical signal proportional to the light intensity. By measuring its magnitude, the sulfur content of the corresponding sample can be calculated.
