Description

Condensation Particle Counters (CPCs) are standard instruments for the determination of the particle number concentration (Stolzenburg and McMurry 1991). Particle activation is mediated by basic physical and chemical processes (Kupc et al., 2013). Recent studies have confirmed that the counting efficiency of ultrafine condensation particle counters is influenced by interactions between the particle material and the working fluid (Kangasluoma et al., 2014).
We present the results of experiments on the influence of the seed particle material on the detection efficiencies and the 50 % cut-off diameters of commonly used CPCs (as published in Wlasits et al., 2020).
