There are various air sampling techniques, each suited for different purposes:
1. Active Sampling: Involves the use of mechanical devices to actively pull air through a filter or a collection medium. - High Volume Air Samplers: Used for collecting large volumes of air over a specific period. - Personal Air Samplers: Worn by individuals to monitor personal exposure levels.
2. Passive Sampling: Relies on natural air movement to collect samples without the use of mechanical devices. - Diffusion Samplers: Capture gases and vapors over time through diffusion.
3. Bioaerosol Sampling: Specifically targets biological particles such as bacteria, viruses, and fungi. - Impactors: Use an air stream to impact particles onto a culture medium. - Centrifugal Samplers: Use centrifugal force to collect particles on a collection surface.
