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

Cascade Impactors TSI

TSI s suite of cascade impactors can collect particles with aerodynamic diameters cutpoints from 10 nm to 10 µm in 3 to 13 different size fractions and at flow rates of 2 10 30 or 100 L/min The number of stages determines the size resolution of the collected samples and consequently determines the level of detail of the data
