ULTRA Passive Samplers

The ULTRA Passive Samplers from SKC are the creative evolution of indoor and ambient air sampling. The patented* ULTRA samples by diffusion and provides low ppb to ppt detection of compounds, including semi-volatile organic compounds (SVOCs). Operation is as easy as sliding the cover open to start sampling and closing it to stop sampling.

  •  
  • Provides results comparable to canisters for EPA Method TO-15
    • No cleaning or certification costs
    • Lower purchase price
    • No expensive shipping
  • Passive alternative for EPA Method TO-17 — no pump required
  • Choice of 5 sorbents for indoor and ambient air sampling, including semi-volatile organic compounds (SVOCs):
    • Anasorb GCB1
    • Tenax TA
    • Chromosorb 106
    • Charcoal (solvent desorption)
    • Carbopack X
  • Slide cover for easy on/off
  • Miniature lightweight sampler is easy to transport — no expensive shipping
  • Validated sampling (uptake) rates
    • For indoor (low air velocity) uptake rates, see Technical Note: Indoor and Outdoor Sampling Rates for Environmental Sampling Using ULTRA Passive Samplers (Contact SKC for details)
  • Built-in blank/correction sorbent section (Also available with sorbent loaded in the sample compartment only, when a blank is not required)
  • Also available as an empty housing with separate sorbent vials for user-filled samplers.
  • Sample integrity:
    • Sonically welded housing seals the sampler
    • Manufactured in an ultra-clean environment
    • Extensive cleaning and quality control procedures
  • Long term sampling up to 30 days reduces temporal variability. Please contact SKC for details.
  • 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 programmes

* US Patent No. 6,607,581
