详细介绍
PSP105型气相色谱仪?
无铅汽油是为了改善汽车排放物中含铅物对环境的污染。而在汽油中加入醚类和醇类和其他含氧化合物可以提高辛烷值及降低挥发性。所加含氧化合物的类型和浓度都有规定，并应加以调整，以便保证达到商品汽油的质量要求。驱动性、蒸气压、相分离，汽车尾气排放和挥发性汽车排放物都与燃料的含氧化合物有一定的关系。另外，苯和芳烃的含量对于汽油质量也非常重要。 国家规定可在汽油中添加10％的变性燃料乙醇，并监测其他醇类和醚类，以达到节能降耗的目的。目前，车用乙醇汽油已经在全国多个省市推广应用，所以乙醇汽油的分析检测也越来越重要。

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 stat.disablede stipulates that 10% of denatured fuel ethanol can be added to gasoline, and other alcohols and ethers can be monitor.disableded 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.
