Conduct a damaging Regulate as test sample, using the chosen pre incubated diluent rather than the test preparation.
For centrifugal air samplers, numerous before scientific studies confirmed which the samples shown a selectivity for much larger particles. The usage of such a sampler could possibly have resulted in greater airborne counts as opposed to other sorts of air samplers on account of that inherent selectivity.
