GC-9560-HS specialized chromatograph for automotive gasolineMeaning and Application:
Adding ethers, alcohols, and other oxygen-containing compounds 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.
In addition, the content of benzene and toluene is also very important for the quality of gasoline.

GC-9560-HS specialized chromatograph for automotive gasolineSummary of the method:

• Analysis of oxygen-containing compounds: Add the internal standard ethylene glycol dimethyl ether (DME) to the sample, first enter the TCEP pre cut column, empty the light hydrocarbons, and then switch between methylcyclopentane and methyl tert butyl ether to allow oxygen-containing compounds to enter the WCOT column. After the tert amyl methyl ether flows out, blow back the heavy hydrocarbon components.
• Analysis of benzene and toluene: Add the internal standard 2-hexanone to the sample, first enter the TCEP pre cut column, and empty C9 and C ratio₉Light non aromatic hydrocarbons are then switched before benzene flows out, allowing benzene, toluene, and 2-hexanone to enter the WCOT column. After 2-hexanone flows out, the remaining components (C₈And C₈The above aromatic hydrocarbons and C₁₀And C₁₀The above non aromatic hydrocarbons
