Automated Analysis of Field-Collected Aerosols


EMSL Project ID
1722

Abstract

We have developed a field portable instrument for automated collection of particles on a time-resolved basis. Essential to this project is having access to automated particle analysis. This capablity is now being added to the EMSL LEO 982 scanning electron microscope. We propose to use this capability to analyze the thousands of particles collected by the field device. We expect to collaborate in developing the best instrument setting, software parameters, information handling, substrate optimization etc., and to co-publish results in appropraite journals.
