Excellent sampling correlation in side-by-side studies with canisters
No cleaning and certification costs
Lower purchase price than canisters
No expensive shipping
Easy on/off sampling — no flow controller or training required

Available with choice of 5 sorbents to better target compounds for indoor and ambient air sampling — including semi-volatile organic compounds

Carbograph 5
Anasorb GCB1
Tenax TA
Chromosorb 106
Charcoal (solvent extraction)

Passive sampler convenience combined with high sensitivity of thermal desorption
- Low ppb to ppt detection of organic vapors in ambient or indoor air
Solvent extraction model available
Sliding cover for easy sampling, no pump required
Rugged, lightweight miniature sampler

Easy to transport
Discreet sampling
Sonically welded housing

Validated sampling rates
High capacity samplers
Manufactured in an ultra-clean environment

Sorbents undergo extensive cleaning and QC procedures

Suitable for long-term sampling up to 30 days

Ideal for vapor intrusion studies, including 7-day and 30-day sample times to reduce temporal variability in indoor air concentrations and improve risk estimates
Lower sampling rates available for long-term studies with secondary diffusion barrier accessory

See the Passive Sampling Guide for sampling rates

SKC introduces ULTRA III Passive Samplers — the creative evolution of indoor and ambient air sampling. The patented* ULTRA III samples by diffusion and provides low ppb to ppt detection of compounds, including semi-volatile organic compounds (SVOCs). ULTRA III Passive Samplers are an economical alternative to SUMMA canisters for EPA TO-15 sampling and show excellent sampling correlation in side-by-side studies with canisters. Operation is as easy as sliding the cover open to start sampling and closing it to stop sampling.

* U.S. Patent No. 6,607,581 :
