1, Product Introduction
The instrument consists of a injector, a cracking furnace, an ultraviolet lamp (original import), a reaction chamber, a photoelectric converter (original import), a micro current amplifier, and a data processing system.When the sample is into the pyrolysis reactor, it is mixed with oxygen and burned, and sulfur was quantitatively converted into SO2.The SO2 is carried by the carrier gas and dehydrated by the dryer to enter the reaction chamber, where the excited state of SO2* is generated by irradiation with ultraviolet light of a specific wavelength, and when the SO2* returns to the basic state, photons (weak fluorescence) are emitted.The emitted light is received by the photomultiplier tube and amplified by the microcurrent amplifier.Data processing system conversion shows a signal proportional to the intensity of the illumination,and total sulfur content of the sample can be determined by measuring the intensity of the emitted fluorescence.
