VOC Chek 575 Series Passive Samplers for ppm-Level VOCs

Orderable Items The Passive Sampler for Organic Vapors collects organic vapors without the use of a pump. The sampler is validated for short-term and eight-hour sampling and 24-hour indoor sampling for some compounds. Use the sampler to test exposure to VOCs such as toluene, tetrachloroethylene, trichloroethylene, xylenes, ethylbenzene, 2-butanone (MEK), hexone (MIBK), benzene, butyl acetates, and styrene. Models exclusive for ethylene oxide and methanol are also available.

  • Decrease sampling costs
    • More sorbent/capacity + validation to 2x exposure level
    • One sampler per 8-hour shift
    • One analysis of a single layer
    • Savings for you
    • Economical sorbent desorption and GC analysis

  • Increase convenience
    • No assembly required for sampling
    • New design for easier sorbent transfer during analysis
    • New reference guide available for laboratories
    • No pump or training required

  • Increase reliability
    • Sampling rates for over 300 compounds in the SKC Passive Sampling Guide
    • Online research reports document performance for legal and compliance issues. Visit www.skcinc.com/reports.asp
    • Specialty samplers available for ethylene oxide (EtO), styrene, and methanol
    • Validated in OSHA methods as a reliable alternative to active sampling
  • Variety of samplers available
    • Only SKC offers a choice of sorbents to better target specific contaminants
    • Proper sorbent selection means no reverse diffusion

  • Superior collection efficiency
    • SKC sorbents have a larger surface area for higher capacities
    • Samplers contain > 300 mg of sorbent much more than other brands

  • Meet ASTM D6246-08 and ANSI/ISEA 104-1998(r 2009) standards

SKC VOC Chek 575 Passive Samplers
Miniature VOC Chek 575 samplers collect organic vapors without the use of a pump. Individual chemicals simply diffuse from the atmosphere into the sampler at a fixed rate. SKC has scientifically validated the sampling rate of the VOC Chek 575 Series passive samplers along with other critical sampling parameters to meet OSHA/ASTM/ANSI requirements. SKC VOC Chek 575 Series Passive Samplers are identified as a viable alternative to active sampling in seven OSHA methods.



Full-shift Sampling with only ONE sampler

The Methanol Passive Sampler collects methanol for up to an 8-hour work shift with superior efficiency. The Methanol Passive Sampler overcomes the short sample times and sample migration concerns of active methods. These samplers are ideal for use in chemical, fuel, wastewater, and hydraulic fracking industries.

Using a VOC Chek Passive Sampler is easy as 1, 2, 3!

VOC Chek 575 Series Passive Samplers
Validated to NIOSH Protocol 1

Passive sampling is quite different from active sampling with sorbent tubes. With this fact in mind, NIOSH established validation protocols for evaluating the performance of passive samplers. 1   Protocol validation was developed so that manufacturers could produce passive samplers that reliably assess airborne levels.

For compliance sampling, it is recommended that only passive samplers with full or bi-level validation be used. Passive samplers with lower levels of validation may be used only if verified by validated sorbent sample tube methods.

Validation Level

Sampler passed stringent testing as outlined in NIOSH and ANSI protocols including desorption efficiency, relative humidity, temperature, concentration, sampling rate and capacity, reverse diffusion, and storage.

The most volatile member of a related (homologous) series of chemicals has passed full validation; therefore, related less volatile series members require only partial validation to achieve the same level of sampling accuracy (see Guild et al. [DOI: 10.1080/1047322X.1992.10390161] or request a copy from SKC).

Passed NIOSH protocol for sampling rate, desorption efficiency, and storage stability.

(Not Validated) Calculated
This calculation of a sampling or uptake rate uses the diffusion coefficient of a specific chemical (D) and the cross-sectional area (A) and length (L) of the sampler’s diffusion path (based on sampler geometry).

Sampler has been validated by OSHA and is referenced in a published OSHA method.
