Airborne biocontamination in cleanrooms - Some aspects on air samplers
2006 (English)In: 37th R3-Nordic Contamination Control Symposium / [ed] Wirtanen, G; Salo, S, ESPOO: TECHNICAL RESEARCH CENTRE FINLAND , 2006, Vol. 240, 421-428 p.Conference paper (Refereed)
In cleanrooms the main source of biocontamination is people. The concentration of airborne biocontamination depends upon the number of people present in a cleanroom, their level of activity, and the clothing systems used. There are several methods of measuring the airborne biocontamination and many published reports show that the results - as number of colony forming units per cubic meter (CFU/m3) - depend on the equipment used. The difference in results between microbiological air samplers often depend upon physical parameters of the samplers. These parameters, together with d50 that is the aerodynamic particle diameter where 50% of the particles are collected and 50% are not collected are discussed. In order to evaluate the collection efficiency of impaction air samplers, a simplified mathematical model will be presented and examples given.
