Rapid Hydrocarbon Speciation and Exhaust Reactivity Measurements using High Speed, High Resolution Gas Chromatography

摘要

The ozone forming potential (OFP) and specific reactivity (SR) of tailpipe exhaust are among the regulated factors that determine the environmental impact of a motor vehicle. OFP and SR measurements require a lengthy determination of a abut 160 non-methane hydrocarbon species. A rapid gas chromatography (GC) instrument has been constructed to separate both the light (C2- C4) and the midrange (C5-C12) hydrcoarbons in less Than 10 minutes.
