Non-Thermal Soot Denuder

Completed Technology Project

Project Description

Non-Thermal Soot Denuder
We propose to develop a non-thermal soot denuder for measuring chemical components of the nucleation mode particulate matter emissions from gas turbine engines, in combination with an Aerodyne Aerosol Mass Spectrometer (AMS). This proposed approach will effectively eliminate the contribution of soot particles to the AMS-measured volatile PM mass spectrum. It is capable of identifying the semi-volatile composition of the nucleation mode particles based on their characteristic mass spectra and also determining the particle size distribution in aerodynamic diameter.
