Pressure Reduction System and Method for Reducing the Pressure of High Pressure Aerosols

Abstract:

A pressure reduction system and methods therefore that include features for reducing the pressure of a high pressure aerosol to ambient pressure without significantly changing the characteristics of the aerosol are provided. In this manner, the non-volatile particulate matter concentration in a sample stream obtained from the aerosol stream at ambient pressure is representative of the non-volatile particulate matter concentration that was present in the aerosol stream at high pressure prior to the pressure reduction.
