Near Real-time Alkene Sensor for Atmospheric Aerosol Chemistry Monitoring


EMSL Project ID
20390a

Abstract

The goal for the proposed project is to be able to take advantage of the current investments made at EMSL for the development of TDS to evaluate the potential for combining the TDS with the current sensor platform developed at MicroET, for the development of a compact, yet effective atmospheric monitoring. Our specific objectives are: (1) Work with Dr. Jay Grate to demonstrate the efficiency of the current TDS system at EMSL in adsorption of ethylene and higher molecular weight alkenes such as isoprene; (2) Evaluate the threshold response of our electrochemical sensor to these alkenes during the desorption cycle; (3) Work with Dr. Mike Alexander to compare against results obtained from proton transfer reaction ion trap mass spectrometry (PTR-MS) system available at EMSL.
