Active air sampling limits.

Active monitoring utilizes microbiological air sampling devices that physically draw a known volume of air over or through a microbial particle collection medium either by impaction impingement. Active sampling involves the use of an air sampling pump to actively pull air through a collection device such as a filter. This leaves determination of the number ofsites for passive air sampling and surface sampling. Passive sampling however does not require active air movement from a pump.

The collected culture can then be incubated and. Active and passive monitoring. Passive air sampling passive air sampling i e settle plates is a frequently. Active there are two primary methods for microbial air sampling.

In active monitoring a microbial air sampler is used to force air into or onto its collection medium e g petri dish with nutrient agar based test media over a specified period of time. Active air sampling sites should be done at the same locations or as close as practical to avoid compro mising the other measure or the product integrity.
