ULTRA Passive Sampler for ppb-Level Organic Vapors SKC

The ULTRA® Passive Sampler offers a choice of four sorbents for indoor and ambient 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.

Compare to canisters for EPA Method TO-15
No cleaning or certification costs
Lower purchase price
No expensive shipping


Passive alternative to EPA TO-17 — no pump required 


Choose from 5 sorbents for indoor and ambient air sampling (including SVOCs)
Anasorb GCB1
Tenax TA
Chromosorb 106
Carbopack X 
Charcoal (solvent extraction) 


Sub-ppb level detection, highly sensitive thermal desorption
Rates 15 times higher than tube-style passive monitors for lower detection limits 


Small, lightweight, and easy to transport 


Validated sampling (uptake) rates
For outdoor uptake, see the Environmental Sampling Guide
See the Passive Sampling Guide 


Built-in blank/correction sorbent section available 


Sample integrity
Sonically welded housing seals the sampler
Manufactured in an ultra-clean environment
Extensive cleaning and QC procedures 


Optional Rate Reducer lowers sampling rates for long-term studies and higher concentration levels observed in soil gas sampling


Allows rapid deployment of multiple samplers for emergency stations 


Easy operation for community action programs
