ULTRA® Thermal Desorption Passive Sampler
The ULTRA® Passive Sampler offers a choice of five sorbents for environmental air sampling. Economical ULTRA samples by diffusion and provides sub-ppb detection of compounds, including semi-volatile organic compounds (SVOCs). Side-by-side studies show ULTRA to be an excellent alternative to stainless steel canisters for sampling benzene, perchloroethylene, xylenes, and toluene. ULTRA is an ideal passive alternative to EPA Method TO-17.
