Technical article discusses improved resolution of benzene, other aromatics and oxygenates in reformulated gasoline using a one-column approach

May 29 2019 Read 353 Times

Merck has published a paper entitled: Analysis of the carcinogen benzene and other components in reformulated gasoline requires high resolution gas chromatography (GC), typically using a two-column switching procedure. Merck have developed SLB-ILD3606, a capillary gas chromatography column engineered for the determination of benzene (and other aromatics) and oxygenates in today’s complex gasoline. This column provides the unique selectivity of the extremely polar SLB-IL111, but with improved peak shapes for oxygenates, resulting in improved resolution for all analytes including benzene.

Selectivity and inertness capabilities were thoroughly tested with aromatic and alcohol mixes as well as reformulated gasoline samples. These observations indicate the SLB-ILD3606 is an effective alternative to the two-column switching procedure currently required for the determination of benzene and other aromatics in reformulated gasoline.
