Description

Analysis Note The measurement of benzene and oxygenate compounds in reforulated gasoline is a common application performed worldwide, both in on-site labs at industrial facilities and also in third-party testing labs. Benzene is listed as a potential carcinogen, and requires monitoring to ensure it is present below a regulated amount. reforulated gasoline contains oxygenates, which are oxygen-containing compounds added to increase combustion. The SLB®-ILD3606 column is able to resolve benzene (and other aromatics) from oxygenates (such as alcohols, ketones, and ethers) and also the aliphatic portion of gasoline.
