Short summary

The aerosol number concentration is essential information for aerosol science. A condensation particle counter (CPC) can robustly provide this information. Butanol is often used as a working fluid in a CPC. We could show that dimethyl sulfoxide (DMSO) behaves equivalently to butanol in terms of the instrument`s counting efficiency, cut-off diameter and concentration linearity. We tested this on different aerosols, including sodium chloride, ammonium sulfate and fresh combustion soot.
