The performance of the Biotest RCS centrifugal air sampler

The index of microbial air contamination

“…Many papers have been published, in which the efficiency of different samplers is evaluated and compared. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] The results are always the same: the final counts differ from one device to the next. Thus 'there is often no obvious choice of the correct sampler to use '.…”

Improved Aerosol Collection by Combined Impaction and Centrifugal Motion

“…Size-selected samples of airborne dust have been collected by several cyclones of different dimensions in series (Smith et al, 1979). For the collection of airborne microorganisms, the Rcuter centrifugal sampler (RCS) (Clark et al, 1981) and other cyclone samplers are used (Errington and Powell, 1969;Upton et al, 1994). One major advantage of the centrifugal method is that cyclones are less subject to particle bounce and re-entrainment.…”

The influence of sampling duration on recovery of culturable fungi using the Andersen N6 and RCS bioaerosol samplers

“…It is not possible to determine the exact d 50 cutpoint of the RCS because the air intake and exhaust of the device share the same orifice. Empirical estimates of the d 50 cutpoint of the RCS range from 5 μm (Clark et al., 1981) to 3–4 μm (Macher, 1989), to below 2 μm (Jensen et al., 1992).…”
