Wall loss experiment description:
Particles are atomized to the chamber and stabilized. SMPS measures the particle profile in the dark.

Wall loss rates calculation method:
Fitting first order decay equation to the measured particle profile at a given size bin.

Frequency of particle loss experiments:

Wall loss correction description:
The derived wall loss rate for each size bin will be applied to derive the total particles including both suspended and on the walls in an experiment.
