Featuring a capillary injection port, a pressure switched (PreVent) “heart cut" instrument configuration and three capillary columns, Model 4080 utilizes a PerkinElmer Clarus^® 690 GC, and offers total flexibility to analyze for any oxygenate or aromatic compound found in gasoline. The same sample can be run twice with different “heart cut" times, and by spreading the components into two analyses, the interferences found with a large number of components are eliminated. Model 4080 meets the requirements set forth in EN 12177, EN 13132 and IP 425/96 with guaranteed detection levels of benzene at 0.05 – 6%, 0/17% - 15% for individual organic oxygenate compounds, and up to 3.7% for total organically bound oxygen.
