Scope of application: Suitable for determining the content of benzene, toluene, ethylbenzene, xylene, C9 and above heavy aromatic hydrocarbons, and total aromatic hydrocarbons in finished automotive gasoline. The separation of aromatic hydrocarbons in finished gasoline is not affected by non aromatic interference. Non aromatic hydrocarbons with boiling points greater than n-dodecane can interfere with the determination of heavy aromatic hydrocarbons above C9. For C8 aromatic hydrocarbons, both para xylene and meta xylene flow out simultaneously, while ethylbenzene and ortho xylene are detected as single peaks. C9 and above heavy aromatic hydrocarbons are detected as a group of peaks. The concentration range of aromatic hydrocarbons determined by the analysis system is: benzene, 0.1%~5% (volume fraction); Toluene, 1%~15% (volume fraction); C8 mono aromatic component, 0.5%~10% (volume fraction); C9 and above heavy aromatic hydrocarbons, 5%~30% (volume fraction); Total aromatic hydrocarbons, 10%~80% (volume fraction). The common alcohol and ether compounds in gasoline do not interfere with the determination of aromatic hydrocarbons. This instrument system * complies with ASTM D5580 and is used for the analysis of aromatic hydrocarbon content in finished gasoline *. Suitable for various types of finished gasoline, with a wide range of applications. The alcohol ether compounds added to gasoline do not interfere with the determination, and the instrument can be expanded to include the determination of oxygen-containing compounds

Cars have brought great convenience to people and made significant contributions to the development of human society. However, at the same time, they consume a large amount of oil resources, emit a large amount of harmful gases, and cause significant harm to the human living environment. Nowadays, motor vehicle exhaust pollution has become the main source of urban pollution, seriously endangering people's health and living environment. Adding ether, alcohol, oxygen-containing compounds, and aromatic hydrocarbons to gasoline can increase octane number and reduce volatility. The types and concentrations of oxygen-containing compounds and aromatic hydrocarbons added are strictly regulated and should be adjusted to ensure that the quality requirements of commercial gasoline are met. The driving force, vapor pressure, phase separation, automobile exhaust emissions, and volatile automobile emissions are all related to the oxygen-containing compounds and aromatic hydrocarbons in the fuel. Therefore, accurate detection of oxygen-containing compounds and aromatic hydrocarbons is of great significance for various aspects such as gasoline quality.
