Methods of Air Sampling
The various methods of air sampling include:
1. Impingement which is trapping of airborne particles in a liquid matrix.
2. Impaction which is forced deposition of airborne particles on a solid surface.
3. Centrifugation which is mechanically forced deposition of airborne particles using inertial forces of gravity.
4. Filtration which is trapping of airborne particles by size exclusion.
5. Deposition which is collection of airborne particles using only naturally occurring deposition process.
