Analyze the microbial quality of air by sampling 100 litres of air at each of the locations mentioned in annexure i using active air sampler carry the pre incubated scda plates and sterile ss head in a ss container to the sampling location.
Active air sampling requires the use of a microbiology air sampler to physically draw a known volume of air over or through a particle collection device and there are two main types.
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.
The following steps describe the way to assemble the passive air sampler.
