GA-EDX-8833S XRF fluorescent sulfur analyzer
1.Introduction
At present, the restriction and control of sulfur content in petrochemical products, especially in oils like diesel, gasoline and lubricant, has become the focus of environmental protection across the globe. The oil sample with high sulfur content, during combustion, will generate sulfur dioxide that further bebomes sulfite or sulfuric acid via chemical reaction to corrode engines.A large amount of sulfur oxides discharged into air is main cause of acid rain. The sulfur in gasoline, after combustion, becomes sulfate attached to noble metal coating of catalyst, and then causes vehicle exhaust to not able to meet statutory standards. It is therefore imperative for us to reduce sulfur contentin gasoline.
GA-EDX-8833S Portable Monochromatic Wavelength Dispersive X-ray Fluorescence Sulfur Meter is the latest high-performance portable meter developed . The instrument conforms to ASTM D7039 (Standard Test Method for Sulfur in Gasoline and Diesel Fuel by MonochromaticWavelength Dispersive X-ray Fluorescence Spectrometry), which is used for detection of sulfur content in gasoline and diesel to meet national V and VI Standards. It also meets sulfur content detection requirements of<GB252-2015 General Diesel Oil>and<GB17411-2015 Marine Fuel Oil>.
Using high-through put full-focus hyperboloid curved crystal, theinstrumentmonochromates target characteristic X-rays from X-ray tube and focuses them on sample to selectively excite light elements within.This technology reduces background interference, improves peak to back ratio, and has lower detection limit.
