Description
For the purpose of collection of ambient air samples for determination of polyaromatic hydrocarbons (PAH), Polychlorinated biphenols (PCB’s), dioxins and furans, and pesticides a high volume sampler is used for this method with a polyurethane foam (PUF) cartridge. Typically samples are collected on the National Air Pollution Surveillance (NAPS) schedule, every six days. Results will not be immediate but rather in the form of laboratory results, days or even weeks later. PUF samplers are named as such because they use a plug of polyurethane foam to trap the target compounds that exist in the vapour phase. A particulate filter is also used to collect the sample in the particulate phase and trap dust and prevent deterioration of the foam.
