Understanding the composition of finished gasoline is paramount to ensure that a safe and quality petroleum product is delivered to downstream oil and gas customers. PerkinElmer’s portfolio of oxygenate and aromatic analyzers are engineered specifically to meet the needs of customers producing finished gasoline products. Our analyzers can be used to determine ether and alcohol additives in finished gasoline products, as well as benzene, toluene, ethylbenzene and other aromatics as required. Trace methanol, acetaldehyde, MTBE, acetone, 2-propanol can also be analyzed in some models. Once installed, samples can be processed immediately, allowing you to optimize instrument up-time and productivity from day one.

Meeting the requirements of ASTM D5580, Model 4005 provides an analytical solution for the determination of benzene, toluene, ethylbenzene and other aromatics in finished gasoline. To meet the requirements specified in the method, two analyses are run independently and summed to determine total aromatic content. In the first analysis, benzene and toluene are determined, mitigating the interference of non-aromatic hydrocarbons with boiling points greater than n-dodecane. The second analysis determines the concentration of ethylbenzene, p/m-xylene, o-xylene and the C9 and heavier aromatics. Aromatic hydrocarbons are separated without interferences from other hydrocarbons in the sample. The C8 aromatics, p-xylene and m-xylene coelute, but ethylbenzene and o-xylene separate. The C9 and heavier aromatics are also measured as a single group. Detection levels for ASTM D5580 are as follows: Benzene (0.1 – 5%), toluene (0.1 – 5%), ethylbenzene (0.5-10%), xylenes (0.5-10%), C9 and heavier aromatics, (5 – 30%), and total aromatics (10 – 80%).
