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.
For users needing to test finished gasoline samples for benzene and toluene by ASTM D3606 with no modifications for oxygenate fuels, Model 4013 utilizes a single channel with the option for an additional channel to create a custom analyzer solution. Aromatic and non-aromatic compounds are measured utilizing a thermal conductivity detector (TCD), with reference to the internal standard methyl-ethyl ketone (MEK). As ethanol co-elutes with benzene, this Model is not suitable for samples containing ethanol. For such samples, Models 4012 and 4014 are suitable options. Detection limits for benzene are 0.1% - 5%, and 2 – 20% for toluene.
Gasoline samples are complex and a single column solution is not always readily available for the required analysis. As such, solutions that have multiple columns, valves, backflushing and heartcutting ability have been developed to overcome these challenging separations. The resulting standardized ...
