A Membrane-Based Apparatus for Measurement of Volatile Particles

INVENTION REFERENCE NUMBER

201102588

  • Analytical-Instrumentation

Measurement of volatile particles emitted by modern jet engines is a daunting task. Besides the complexity in sampling jet aircraft exhaust, the main difficulty lies at how to faithfully capture the phase-partition dynamics of volatile particles as they travel downstream from the engine exhaust nozzle. As a result, the physico-chemical properties of the exhaust are also transformed. We have developed a sampling instrument that aims at enabling study of the phase-partition dynamics. This new apparatus enables high-efficiency measurement of volatile particles produced by combustion processes. This new apparatus also permits direct measurement of the volatilized species removed from the particulate phase, which was impossible to do with any thermodenuding technology commercially available at the present.
