ASTM D5453 Ultraviolet Fluorescence Sulfur Content

 

Applicable standard
The instrument complies with ASTM D5453, SH/T 0689 and other standards for the determination of total sulfur in crude oil, distillate, petroleum gas, petrochemical products, food and so on.

 

Product information

The instrument adopts the ultraviolet fluorescence method to determine the principle: after the sample to be tested is introduced into the pyrolysis furnace, the sample is completely vaporized and oxidatively cracked at a high temperature of about 1050 ° C, wherein the sulfide is quantitatively converted into sulfur dioxide. The reaction gas is carried by the carrier gas, and the water is removed from the reaction chamber through the membrane dryer. Sulfur dioxide is exposed to ultraviolet light of a specific wavelength, and the absorption of such rays causes some electrons to turn to high energy orbits. Once the electrons return to their original orbit, the excess energy is released as light and is detected by a photomultiplier tube at a specific wavelength. The emitted fluorescence is completely specific to the sulfur and is related to the sulfur content of the original sample. In direct proportion. After being amplified by the micro-current amplifier and processed by computer data, it can be converted into an electrical signal proportional to the light intensity. By measuring the size, the sulfur content of the corresponding sample can be calculated.

 

Features

● Windows operating platform, man-machine dialogue, easy to operate.

● The core detector of the instrument is manufactured by the patented technology of anti-leakage and anti-leakage, which makes the instrument have the advantages of high sensitivity, low noise, wide linear range and strong anti-interference ability.

● The instrument adopts international popular circuits and imported devices (UV lamps, filters, membrane dryers, etc. are imported), the performance of the whole machine has reached the international advanced level, which is superior to domestic similar products and can replace imported.

● High pressure can be adjusted freely. Standard calibration can be adjusted by single point, which is convenient, fast and accurate.
