Automated, High-resolution Mobile Collection System for the Nitrogen Isotopic Analysis of NOx Paul K. Wojtal1,2, David J. Miller2,3, Mary O'Conner1, Sydney C. Clark2,3, Meredith G. Hastings2,3 1Department of Chemistry, Brown University, 2Institute at Brown for Environment and Society, Brown University, 3Department of Earth, Environmental, and Planetary Sciences, Brown University Previous work suggests that the nitrogen isotopic composition of atmospheric nitrogen oxides might distinguish the influence of different sources in the environment. We report on an automated, mobile, field-based method for the high collection efficiency of atmospheric NOx for N isotopic analysis at an hourly time resolution.
