The ULTRA® Passive Sampler offers a choice of four sorbents for environmental air sampling. The ULTRA samples by diffusion and provides low ppb to ppt detection of compounds, including semi-volatile organic compounds (SVOCs). Use the ULTRA as an alternative to stainless steel canisters for green building certification, fenceline monitoring, product emissions, vapor intrusion, and near roadway, traffic, public health/asthma, and school zone studies.
