wall_loss_experiment_description: 'Particles are generated (see generation methods) and dried and neutralized if needed (for aqueous solutions Collision-type atomizer). Chamber is placed in "batch mode" meaning no flow in or out.  Particle concentrations are monitored with an SMPS with 2-min scans for 45-60 minutes. Care is taken to not touch or rub the Teflon bag to avoid inducing static charges during experiments, which could change the particle loss rates.'
wall_loss_rates_calculation_method: 'Integrated particle volume is calculated as a time series in custom IGOR Pro software. A first order exponential decay coefficient is fit to the data with Igor Pro.'
frequency_of_particle_loss_experiments: 'Typically whenever seeding an experiment. Otherwise at least once for a series of experiments without seeds.'
wall_loss_correction_description: 'First-order integrated particle volume correction. Integrated volume particle loss coefficient applied to integrated mass or volume time series to correct for chamber partile losses. SOA experiments corrections assume the seed plus condensed SOA decay at the same rate through the experiment.'
