Acquisition of Proton-Transfer-Reaction Time-Of-Flight Mass-Spectrometer (PTR-TOF-MS) for Airborne Volatile Organic Chemical Concentration and Flux Measurements
Abstract
Funds are provided for acquisition of a state of the art Proton Transfer Reaction Time Of Flight Mass Spectrometer (PTR-TOF-MS). The instrument will be integrated onto the Naval Postgraduate School (NPS) Twin Otter research airplane for measuring concentrations and fluxes of a broad range of volatile organic compounds (VOCs). The PTR-TOF-MS instrumentation will enable simultaneous airborne flux measurements of a full range of natural and anthropogenic VOCs (100s of VOC species, with detection limits of order 1 ppt in 1 sec) providing novel capability to spatially map sources of VOCs and their atmospheric effects. The PI will implement this new technology enabling direct airborne measurements of VOC concentrations and emissions on spatial and temporal scales that are optimal for detecting specific sources, and studying their role in regional air chemistry, secondary aerosol formation, clouds, and haze.
