Sampl'air from AES Chemunex is a high performance but affordable impaction based air sampler for the monitoring of airborne contaminants.
Its performance has been evaluated according to the ISO 14698-1 standard by the UK Health Protection Agency (HPA) in Porton Down. The Institute said in its conclusion that: âThe results of the physical
testing of the Samplâair obtained were very consistent and the standard deviations were of a low order for aerobiological studies. The Samplâair was found to be efficient (115.9% - 138.5%) for collecting particles containing bacterial cells in the size range 2.5- 12.5 ìm compared to membrane filters.
The efficiency of the Samplâair for lower particle size (0.8- 1.3ìm) was found to be excellent (60.5- 66.2%).This suggest that the d50, the particle diameter at which the sampler efficiency drops below 50%, is
approximately 0.5 ìm. The percentage of microbiological particles found in indoor environments at this particle size is extremely low and therefore the Samplâair should be capable of collecting over 99% of particles occurring in this environment.
The Sampl'air is available in two versions, Lite and Pro, the latest offering total traceability functions. More information is available on the dedicated home page.
