Ambient reactive nitrogen is a mix of organic compounds that contain nitrogen and inorganic compounds including nitric acid, nitrate, ammonia, and ammonium.  These various forms of nitrogen are found in oxidized and reduced forms and in both the aerosol and gas-phases.  The aerosol-phase reduced nitrogen is predominately thought to include ammonium and amines.  In ambient samples the ammonium concentration is often routinely determined, but the contribution of amines is not.  In addition, in the traditional chromatography methods currently used to measure ammonium and other common inorganic ions there is significant overlap with amines that is not accounted for.  Therefore, we have developed a method to discretely measure amines from ambient aerosol samples.  It employs ion chromatography using a Dionex CS-19 column with conductivity detection and a 3 step methanesulfonic acid eluent separation.  This method allows for quantification of 18 different amines, including the series of methylamines and ethylamines as well as the different isomers of butylamine.  Here we will present the details of the method.  We will also examine data from the analysis of ambient filter samples collected in Rocky Mountain National Park (RMNP) and Greeley, CO as well as from biomass burning source samples.  Almost all of the amines quantifiable by this technique were measured regularly when this method was applied to the samples collected in RMNP and Greeley.  The sum of the amines was generally ~0.02 µg/m³.  This increased to 0.04 and 0.09 µg/m³ at RMNP and Greeley, respectively, when being impacted by biomass burning smoke, largely due to observable increases in methylamine and dimethylamine.
