Аcatalytic stripper is a heated catalytic element used to remove the particle and gas-phase semi-volatile fraction of an aerosol.


Diesel, locomotive, and gas turbine exhaust contain a complex mixture of solid particles and semi-volatile material that is found in both the particle and the vapor phase. Physical and chemical  characterization of these exhaust aerosols in the environment enables a better understanding of potential health effects, effectiveness of alternative combustion  technologies and emission control devices, and the impact of new fuel and lubricant formulations on emissions. These measurements are enabled through the use of catalytic stripper (CS) technology.
