Passive Samplers

SKC remains on the leading edge of passive sampler design and validation. In response to the NIOSH Validation Protocol for Passive Samplers published in 1986, SKC developed the first fully validated diffusive samplers. The SKC 575 Series samplers are available in a choice of solid sorbents to better trap designated compounds. SKC offers research reports that document sampling reliability for target compounds. U.S. OSHA also lists 575 Series passive samplers in published methods. As of 2011, 575 Series samplers with specialty or chemically coated sorbents are available for collecting compounds such as ethylene oxide and styrene. SKC leads the way in passive samplers using chemically coated filter paper as the collection medium. The UMEx 100 is listed in OSHA Method 1007 for formaldehyde. SKC has validated the UMEx 400 for aliphatic amines and the UMEx 200 for sulfur dioxide and nitrogen dioxide. Finally, SKC pioneered the concept of passive samplers using thermal desorption for sub-ppb level detection of organic compounds with its introduction of ULTRA passive samplers. Thermal desorption is also employed in an SKC passive sampler to measure nitrous oxide in health care settings.
