What's New

Eurofins Air Toxics Inc. now offers analysis of Radiello® passive diffusive air samplers.  Passive diffusive samplers offer solutions to many air sampling applications including environmental monitoring, ambient and outdoor air monitoring, industrial hygiene, industrial air quality (IAQ),  and personal sampling.

Our 30,000 sf. facility is the largest air testing laboratory in the country providing testing services on a national and international level.   Eurofins Air Toxics Inc. has partnered with the EPA, Navy, and other governmental agencies to validate passive technology for use in providing technically defensible analytical data for a wide spectrum of analytes. Our extensive experience supports passive sampling projects throughout the United States, Europe, Asia, and the Middle East.  Recently, we supported a significant indoor air quality characterization study that involved the analysis of over 1500 Radiello® samplers.

Sampling with passive devices does not require the use of pumps and it can be performed anywhere and at a very low cost. The radial design offers higher capacity and faster uptake/sampling rates than traditional passive monitors.

Eurofins Air Toxics Inc. Maintains an extensive inventory offering immediate delivery.  No waiting for the supplier.

Passive sampling should be considered for projects requiring accuracy, low detection limits, and simplicity.


  • Ambient air monitoring
  • Indoor air monitoring
  • Workplace monitoring
  • Fenceline/Perimeter monitoring 
  • Air monitoring in remote locations lacking electrical power


  • Low detection limits
  • Flexible exposure times (15min-30days)
  • High precision and accuracy
  • Suitable for sampling a wide range of gaseous components
  • Reusable components
  • Wet weather use

We continue to expand our sorbent capabilities and have added to both our TO-17 product line and our passive sampling solutions. Total Petroleum Hydrocarbon fuel identification and characterization are now available by EPA Method TO-17, encompassing middle distillate fuels such as diesel, jet fuel, mineral spirits and kerosene. Carbon range fractionation, quantification of aliphatic and aromatic hydrocarbons, and a wide range of compounds of concern from naphthalene to pyrene are also achievable using TO-17.

We also offer a wide array of passive sampling solutions for indoor and outdoor air. Our technical team can assist you in choosing the appropriate passive sampler to meet your data quality objectives. While we have numerous options for volatile organic compounds (VOCs), we have recently added capabilities to collect and analyze for ammonia and hydrogen sulfide using passive samplers.
