Tisch Environmental's passive air samplers are used for the collection of persistent organic pollutants (POPs) in ambient air. These instruments can be deployed quickly in any location and are maintenance free.
Passive air samplers house a polyurethane foam disk (PUF) which is uniformly porous to allow gaseous chemicals to penetrate. The samplers with the polyurethane foam plugs are deployed and collect the POPs in ambient air. The PUF disks are later removed from the device and transported to a lab for analysis.
