The basic suitability of two collection systems with wind direction-independent ring slot probes for the isokinetic sampling of bioaerosols in open-ventilated barn systems was investigated: firstly, in a test channel a newly developed ring slot inlet for a modified emission impinger with subsequent quantification of the collected cells, and secondly, in a cattle barn a standardized E-dust collection device with subsequent fluorometric quantification of the DNA collected. In principle, both devices are suitable for the respective applications. With the E-dust collection head, sampling under isokinetic conditions is only possible at low wind speeds, with the newly developed ring slot probe even in strong winds. Further trials are to follow in order to test the practical suitability of the systems over longer periods of time.
