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 toluene, tetrachloroethylene, trichloroethylene, xylenes, ethylbenzene, 2-butanone (MEK), hexone (MIBK), benzene, butyl acetates, and styrene.


  • Newly designed housing for easier analysis

  • No assembly required

  • Accurate and reliable — Proven performers
  • Save time and money
    • Collect most compounds with one sampler for up to a full 8-hour workshift eliminating multiple trips to the worksite
    • One sampler + one analysis = money saved
    • Economical solvent desorption and GC analysis

  • Variety of samplers available
    • Only SKC offers a choice of sorbents to better target specific contaminants
    • Proper sorbent selection means no reverse diffusion

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

SKC VOC Chek Passive Samplers are validated for a full 8 hours, that's TWICE the limit value! This assures the integrity of the sampler, so you only need ONE sampler to get a true 8-hour TWA!

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

1. Remove front cap.

VOC Chek 575 Series Passive Samplers
Validated to NIOSH Protocol 1


Validation
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

Full
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.

Bi-Level
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).

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

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).

About OSHA Testing
After extensive testing on the sampling rate variations among diffusive samplers, OSHA has released the following methods that specify diffusive (passive) samplers including SKC Cat. No. 575-002:
  • Toluene — Method 111 (1998)
  • Tetrachloroethylene and Trichloroethylene — Method 1001 (1999)
  • Xylenes and Ethylbenzene — Method 1002 (1999)
  • 2-Butanone (MEK) and Hexone (MIBK) — Method 1004 (2000)
  • Benzene — Method 1005 (2002)
  • Butyl acetates — Method 1009 (2007)
  • Styrene — Method 1014 (2009)

OSHA continues its work on passive method development based on the premise that diffusive samplers are a viable alternative to tube/pump sampling.
