Catalytic strippers can be used to determine the solid and semi-volatile particle concentrations in engine exhaust in the laboratory or during on-board vehicle measurements. Engines burning gasoline, diesel fuel, and natural gas all produce solid and semi-volatile particles. For oxygen rich combustion such as diesel, engine exhaust can be directly sampled by the catalytic stripper and measured by a suitable instrument. However, for oxygen lean combustion such as gasoline, engine exhaust must be diluted prior to measurement so that the oxidation reaction can occur. The residence time in the catalytic stripper is low, so this device can be used in transient engine exhaust measurements. Another application is measuring emissions from gas turbines in laboratory and ambient environments.
