Detailed introduction
PSP105 Gas Chromatograph
Unleaded gasoline is designed to improve environmental pollution caused by lead in vehicle emissions. Adding ethers and alcohols and other oxygenates to gasoline can increase octane number and reduce volatility. The type and concentration of the oxygenated compounds added are regulated and should be adjusted to ensure that the quality requirements of commercial gasoline are met. Driveability, vapor pressure, phase separation, vehicle exhaust emissions and volatile vehicle emissions all have a certain relationship with the oxygenates of the fuel. In addition, the content of benzene and aromatics is also very important for gasoline quality. The state stipulates that 10% of denatured fuel ethanol can be added to gasoline, and other alcohols and ethers can be monitored to achieve the purpose of energy conservation and consumption reduction. At present, ethanol gasoline for vehicles has been popularized in many provinces and cities across the country, so the analysis and detection of ethanol gasoline is becoming more and more important.
