Table of Statistical Corrections According to Feller for the BioCapt® Microbial Impactor in Microbial Air Sampling
This application note uses the principle that, as the number of viable particles — colony forming units (CFUs) — impact on an agar plate increases, the probability that viable particles will enter unoccupied space decreases. The values within Tables 1 and 2 are shown at flow rates of 25–50 LPM and 100 LPM. BioCapt microbial impactors are used on all Particle Measuring Systems instruments including the MiniCapt® Mobile Microbial Air Sampler and the MiniCapt Remote Microbial Air Sampler. The BioCapt Single-Use has the same pattern of the BioCapt Microbial Impactor and therefore, the Feller’s table is applicable to this unique BioCapt Single-Use impactor for 25–50 LPM flow rates. The impactor’s design enables the capture of microbiologically viable particles on a suitable media surface for incubation and enumeration.
