Abstract

The complex photochemical transformations of biogenic hydrocarbons such as isoprene and of anthropogenic hydrocarbons such as aromatics are an important source of carboxylic acids in the troposphere. The identification of unknown carboxylic acids can be difficult, however, due to the lack of standards as well as poor sensitivity and lack of selectivity of existing techniques. In this study, we describe the development of a method to analyze ...
