Passive Samplers for Indoor and Ambient Air

Beacon Environmental can target a broad range of compounds using sorbent filled stainless steel tubes to passively collect VOCs and SVOCs in ambient and indoor air
Beacon Passive Sampler following established ASTM methods, as well as other international protocols. Passive sorbent samplers do not require pumps or electricity and can be used to collect samples over a brief period of time (e.g., one hour) to weeks (e.g., 14 to 30 days), thereby providing a time-integrated concentration in units of ug/m3 or ppbv.

A broad range of VOCs and lighter SVOCs can be targeted using passive samplers and because the samplers can be exposed for extended time periods, low reporting limits in the sub-ppbv range are achieved. Passive diffusion samplers are analyzed by Beacon Environmental following EPA Method TO-17.

Benefits of Passive Samplers

  • Time Integrated
  • Collect sample over one or more days… or weeks
  • Easy to use – No pumps or regulators required
  • Target chlorinated and petroleum compounds
  • Analysis by EPA Method TO-17 (TD-GC/MS)
  • Accurate and ReliablePassive Diffusion Samplers
  • Sensitive – Detection limits in the ppt range
  •  

    "It is estimated that the use of passive samplers can reduce costs by as much as 50 percent compared to traditional sampling."  Source: The NAS Jax Environmental Restoration (ER) Partnering Team Report, 2014.

     

    Beacon is NEFAP accredited for the collection of air samples using passive samplers and is also DOD ELAP And ISO/IEC 17025 accredited for the analysis of these samples following US EPA Method TO-17.
