Product Introduction:

petrifactionAnalysis of Aromatic Hydrocarbons in Finished Gasoline Gas Chromatography G60-DSSuitable for determining benzene, toluene, ethylbenzene, xylene in finished automotive gasolineC₉, andC₉The content of heavy aromatic hydrocarbons and total aromatic hydrocarbons mentioned above. 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 interfereC₉Determination of heavy aromatic hydrocarbons. aboutC₈Aromatic hydrocarbons, para xylene, and meta xylene flow out simultaneously, while ethylbenzene and ortho xylene are detected as single peaks.C₉Use the above heavy aromatic hydrocarbons as a group for peak detection.

The range of aromatic hydrocarbon concentrations determined by the analysis system is: benzene,0.1%~5%(volume fraction)Toluene,1%~15%(volume fraction)；C₈Single aromatic component,0.5%~10%(volume fraction)；C₉Above 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.

The instrument system complies withASTM D5580，SH/T 0693-2000Method for determination of aromatic hydrocarbon content in gasoline (gas chromatography method); Analysis of Aromatic Content in Finished GasolineIt is indispensable.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 also be extended to include the determination of oxygen-containing compounds.

To meet ASTM standardsD5580Method standards andNational and related industry standardsSH/T 0693Method standards: We rigorously debug and test every analyzer that leaves the factory.
