Short summary
Nitrogen oxides are commonly measured by selective thermal dissociation (TD) to NO2, which can be quantified by optical absorption. Quantification of peroxynitrates (RO2NO2) by TD methods, however, is challenging in ambient air since NO2 is usually more abundant than RO2NO2. Here, a method to boost the sensitivity of TD instruments by chemical amplification following addition of ~ 1 % ethane and ~ 1 ppm NO to the inlet is presented. Advantages and disadvantages of the new method are discussed.
