GB/T 33465-2016 was approved and issued on December 30, 2016 by the **General Administration of Quality Supervision, Inspection and Quarantine** and the **Standardization Administration Committee**； A training session on the GB/T 33465-2016 standard will be held from March 22 to 24, 2017, in Shandong Province by the secretariat of Standardization Committee TC374. The detection of harmful elements such as silicon and chlorine in gasoline has long posed a challenge to the testing and analysis professionals in our gasoline industry, and the main reasons for this are the lack of appropriate detection methods and inconsistencies among these methods. GB/T 33465-2016 \"Determination of chlorine and silicon in gasoline by inductively coupled plasma emission spectrometry\" specifies not only the method for detecting silicon in gasoline but also the method for detecting chlorine in it, thereby filling a gap in testing methods in this field and providing a standardized approach for the detection of silicon and chlorine in gasoline, which is of great significance. SPECTRO from the German company Spektrum Instrumente GmbH (the official agent in China: Huapu General) was one of the organizations involved in formulating this standard; its SPECTRO ARCOS ICP spectrometer, manufactured in Germany, is the only instrument that fully complies with this standard. SPECTRO ARCOS analysis wavelength range: 130-770nm ； Super powerful 2KW operating power ； Direct injection of normal-temperature gasoline does not cause stalling ； A gasoline full-injection system is available as an option ； Patented technology for argon-filled closed-cycle light chamber ； Excellent sensitivity and stability ； Successfully meets the national standard requirement of Cl 134.724nm ； Detection at 251.612nm/288.158nm ； It fully possesses the capability to expand to the detection of more than 70 other elements such as Pb, Fe, Mn, P, S, As, Cu, etc ；
Sinopec is also testing for chlorine and silicon content, but are these two elements really necessary to be tested?
I’m worried that external crude oil might contain other substances; surely crude oil from regular refineries is tested.
There are precedents for testing both silicon and chlorine, as these two elements can directly cause problems in vehicles. Although they are not added by legitimate refineries, it is still necessary to avoid their presence in chemically blended oils; therefore, it is essential to test oils purchased from unofficial sources
