Short summary
In this paper we show that chemical similarities between the seed particle material and the working fluid have an impact on the detection efficiency of commonly used CPCs. A remarkable set of CPCs, including the newly developed V-WCPC 3789, was tested. Among others, reproducibly generated organic seeds based on beta-caryophyllene were used. Theoretical simulations of supersaturation profiles were successfully linked to measured data.
