Short summary
The identification and quantification of compounds within an atmospheric particle can be difficult to achieve. We present a supercritical fluid chromatography method to separate these compounds prior to mass spectrometry analysis. The aqueous methylglyoxal–ammonium sulfate system was used as a proxy for atmospheric aerosol; polar columns combined with a carbon dioxide and methanol mobile phase provided the most efficient separation. This method can be extended to other atmospheric systems.
