    experiment_goals: 'This experiment serves as a no-organic control for experiments on 11/16/21 and 11/19/21, to examine the dark size-dependent loss rates of ammonium sulfate aerosol in the chamber while filter collection is in progress.'
    experiment_summary: 'The chamber was humidified to ~80% RH; ammonium sulfate was introduced by atomization. Filter collection proceeded for ~6 hours and particle loss rates were measured during that time.'
