To my knowledge the Andersen sampler requires a flow rate of approx. 28 Liter per minute, whereas impingers run at approx 12 to 15 liter per minute. So if you choose a pump, make sure that it has the appropriate flow rate.

Hi

I work for Viridor, a large waste management company in the |UK, with about 11 composting operations.

We use the AirChek XR5000 pump and the standard IOM heads http://www.skcltd.com/index.php/air-sampling-pumps

we monitor in line with EA/REA protocols
