the limit control of sulfur content in petrochemical products, especially in oil products (such as gasoline, diesel oil, lubricating oil, etc.) has become the main focus in environmental protection. according to the latest china environmental protection agency regulations in petrochemical industry, automotive gasoline total sulfur index dropped from 1000pmm to 500ppm, the current national standard ⅳ sulfur content index has dropped to 50ppm. ordinary diesel index drops from 2000ppm to the current 350ppm. in the meantime, the china maritime safety administration has stipulated that the sulfur content of the fuel used by vessels in the emission control zone shall not exceed 0.5% m/m (5000ppm).
performance advantage
lanscientific pedx® oil is a high performance, portable xrf analyzer that provides the energy industry with the perfect sulfur elemental analysis method for analyzing elemental content in oils such as lubricants, diesel fuels, jet fuels, kerosene, other distillates, volatile oils, residual oils, hydraulic oils, crude oils, unleaded petrol, alcoholic gasoline, biodiesel. also, it can check the existence of elements content, wear elements, pollutants and sulfur content in other similar petroleum products. it can be used in any place, providing safe, high-quality sulfur content analyzing condition for liquid, solid or gas samples.

application areas
lanscientific pedx® oil portable analyzer is used for the analysis of fuels, oils, additives and other fluids in the petrochemical, heavy traffic, power generation, aerospace, crude oil exploration, marine and other industries.
specific applications are as follows:
sulfur content analysis of marine fuels: monitoring of sulfur content in the sulfur dioxide emission control area (seca). special fuel quality regulations emissions control areas exist in sox emission control area (sox eca or seca), including ports and coastlines.
petroleum refining industry: determining total sulfur in fuels and crude oil, or tracing impurities metals in refinery catalysts.
refinery: used for hydrofining units and blending systems.
oil pipeline: used for oil interface judgment and tank contamination judgment.
wear elemental analysis: accurate detection of additives containing al, si, p, s, ca and zn in various engine oils, engine oils, fuels and system oils. according to the concentration of different elements, determine the wear of metal machinery and the necessity for oil replacement.
additive analysis: analyzing high-quality lubricants (mixed based on a special formulation of organic, metallic additives) for precision equipment at extreme temperatures and loads.
hydrocarbon analysis: measuring calcium, sulfur, magnesium, aluminum, phosphorus, silicon, chlorine, etc. in a certain concentration of hydrocarbons and aqueous solutions.
