The maximum particle size measured depends on the detection limit of the FSSP-300; if particle concentrations drop below approximately 10 −2 scm −3, the instrument is not able to detect the particles. In our study, we define the maximum particle size, D p, max, as the size of the particles that occur at a concentration of 10 −2 scm −3.
