A brief history of the impaction sampler
· The Andersen multistage impactor took the technology to another level as it was able to grade by particle size. Initially developed for assessing size distribution of viable particles in the 1950's, the Andersen became the base for the modern microbial sieve samplers of today. At the same time, Bourdillon et al developed a slit sampling ...

Air sampling in hospitals
Certain samplers are used for special studies such as the Andersen stackedsieve impactor or the liquid impingers. Lately, samplers have been developed which due to their size and weight are more useful to the hospital microbiologist and epidemiologist than the older slit samplers. the Ross Microban sieve sampler and the Biotest Reuter Centrifugal Sampler were tested in comparison with the ...

Suppliers of intruments for air sampling and air monitoring
In a typical impactor sampler air is drawn into a sampling head by a pump or fan and accelerated, usually through a perforated plate (sieve samplers), or through a narrow slit (slit samplers). This produces laminar air flow onto the collection surface, often a standard agar plate or contact plate filled with a suitable agar medium. The velocity of the air is determined by the diameter of the ...

Particle Impactor Sampling Guide
Particle Impactor Sampling Guide This method of air sampling involves drawing a measured volume of air over culture media in petri dishes. The petri dishes are incubated in the laboratory so the organisms impacted on the plate can grow. The fungi or bacteria are counted and identified. This method commonly uses the Andersen N6 Impactor TM, shown at right. .
