A brief history of the impaction sampler

The Andersen multi-stage 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.

Viable particle samplers have been generally used to collect and assay aerobic species of bacteria and fungi. Even though many viable samplers, including the Thermo Fisher Scientific Andersen Viable Cascade Impactor (ACI), will collect some virus particles, there is no convenient, practical method for the cultivation and enumeration of these particles. There are two constraints on all viable ...

Andersen Cascade Impactor (ACI) - Copley Scientific

The APSD measurement of DPIs is typically performed under the same conditions as DDU testing, however a Preseparator is typically interposed between the induction port and stage 0 of cascade impactor to capture the large, non-inhalable carrier particles, to prevent impactor over-loading (when using an NGI or ACI). As for delivered dose testing of DPIs, test flow rate is set on the basis of a 4 ...

Air Samplers for Microbiological Monitoring of Air Quality

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 ...
