Semivolatile organics in engine exhaust
Measurements of the emissions of organic compounds from fossil fuel combustion generally focus on species that are high in volatility (VOCs) as well as those that are extremely low in volatility (as particulate matter). In between these two extremes are semivolatile organics and intermediate-volatility organics, which can represent a large fraction of the total emissions but are rarely measured. The Kroll group has developed a new instrument for the measurement of these compounds, which is providing new insights into their emissions from various sources. Recent studies have focused on the emissions from diesel engines and commercial aircraft.
