Gas chromatograph for detecting aromatic hydrocarbons in gasoline

The pollution of the environment caused by the use of gasoline has become increasingly serious with the rapid development of China's economy, especially with the rapid increase of motor vehicles. The emission of automobile exhaust has become the main source of atmospheric pollution, seriously endangering people's health and living environment. Adding oxygen-containing compounds (alcohols, ethers) to gasoline can increase octane rating and reduce volatility. The type and concentration of oxygen-containing compounds added are specified and should be adjusted to ensure that they meet the quality requirements of commercial gasoline. The driving force, vapor pressure, phase separation, automobile exhaust emissions, and volatile automobile emissions are all related to the oxygen-containing compounds in the fuel. Therefore, accurate detection of oxygen-containing compounds is of great significance for various aspects such as gasoline quality.

GC-7890 gas chromatographAnalysis of oxygen-containing compounds and benzene derivatives in gasoline using gas chromatography for the determination of alcohol and ether compounds in gasoline; Determination of benzene and toluene; At the same time, addition can also be used for the analysis of aromatic hydrocarbons. It is an ideal gas chromatograph for applications in the petrochemical industry, refineries, and quality supervision and inspection related fields. This scheme has the advantages of simple operation, good linear correlation coefficient, high accuracy, high precision, and low cost, which is of great practical significance for improving the production method of gasoline and product quality control in industrial production processes.
