Short summary
Chemical ionization mass spectrometry measurements of clusters formed from sulfuric acid and dimethylamine or various diamines show that these clusters are not as efficiently ionized by nitrate as they are by acetate. These clusters are atmospherically relevant, and our results suggest that traditional methods may under-measure cluster concentrations by up to a factor of 10.
