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
  • Anasorb CSC (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: Low Velocity Sampling Rates for Environmental Sampling Using ULTRA Passive Samplers
• 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.
• Allows rapid deployment of multiple samplers for emergency stations
• Easy operation for community action programmes
