ASTM D5453 UVF Ultraviolet Fluorescence Oil Sulfur Tester
for Petroleum Sulphur Content
The UV fluorescence sulfur content tester is an analytical instrument used to accurately determine the sulfur content in various samples.
The sample is sent to a high-temperature cracking furnace, where cracking and oxidation reactions occur at high temperatures (usually around 1050 ºC), where sulfides are quantitatively converted into sulfur dioxide. The reaction gas is carried by a carrier gas and enters the reaction chamber after being dehydrated by a membrane dryer. Sulfur dioxide is irradiated with ultraviolet light of a specific wavelength, absorbs the radiation, and the electrons turn to high-energy orbitals. When the electrons return to their original orbitals, excess energy is released in the form of light, producing fluorescence that is specific to sulfur and proportional to the sulfur content in the original sample. Finally, it is detected and received by a photomultiplier tube at a specific wavelength, amplified by a microcurrent amplifier and processed by a computer to convert it into an electrical signal proportional to the light intensity, thereby calculating the sulfur content of the sample
The Ultraviolet Fluorescence Oil Sulfur Tester Instrument has the following main features:used the fluorescence excitation source of imported,membrane dryer,filters,metal encapsulated photomultiplier tube and has high sensitivity, fast, stable, high accuracy, consistency, etc.Advanced temperature control system: two position warming up respectively and wound inside type tubular furnace. Warming up rapid and stable.
The entire reaction process can be expressed as follows:
Under certain conditions, the fluorescence intensity generated in reaction is in direct proportion to production quantity of S02. The amount of S02 is in direct proportion to the total sulfur content of the sample, so can measure the fluorescent intensity to determine the total sulfur content of the sample.
GD-5453 Fluorescence Sulphur Analyzer works as follows:
1. Host:
1.1 Pyrolysis reaction:
The sulfide in samples convert into SO2 has occurred in this part. The temperature shows two section of furnace temperature by meters,temperature control accuracy ± 1%. Flow control unit can control three-way, adjustment range is as follows:
O2 (Pyrolysis) 50 ~ 500 ml/min
O2 (Carrier gas) 30 ~ 300 ml/min
Ar (Carrier gas) 30 ~ 300 ml/min
1.2 Detector:
Complete fluorescent signal detection, amplification, and accept the computer control, sent the signal to computer for processing.
2. Computer systems:
Computer systems including host, monitor, printer, keyboard, mouse and the corresponding computer software.Complete signal processing and control, to provide samples of the intermediate result and final result of GD-5453.
3. Injector:
The injector put on the right side of the temperature control and ensure constant sample.Users can select the speed in 0.3 ul / sec ≈ 1.2 ul / sec according to the analysis required.
