Short summary
We investigated the chemical retention of water-soluble organic compounds in Beijing aerosols using an acoustic levitator and drop-freezing experiments. Samples from PM2.5 filter extracts were frozen at -15 °C in an acoustic levitator without artificial nucleators and analyzed using ultra-high resolution mass spectrometry. Our findings reveal a non-normal distribution of retention coefficients that differs from current literature on cloud droplets.
