  • Samplers contain a minimum of 300 mg of sorbent — much more than other brands
  
  
• Sampling flexibility
  • Validated for short-term and 8-hour sampling
  • Suitable for 24-hour indoor air sampling for some compounds
  
  
• Proven results
  • Extensively tested and documented
  • Research reports for 20 compounds available
  
  
• So easy to use!
  • No pump or training required
  
  
• Meet ASTM D6246-98 and ANSI/ISEA 104-1998 standards
  


• Identified as viable alternative to active sampling in seven OSHA methods

SKC 575 Series 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 badge to get a true 8-hour TWA!

1.  Remove sampler from pouch.
2.  Record start time, remove cap, and attach to a worker or at a location.
3.  After sampling, cap sampler and record stop time. Send the sampler to an accredited laboratory for analysis.

Full

Passive monitor has passed all NIOSH protocol validation requirements for sampling rate, desorption efficiency, humidity effects, reverse diffusion, storage stability test for reactive compounds whose stability is suspect, and a factorial study that includes interfering compounds. This is the most rigorous test possible and includes all parameters that can affect sampling accuracy (formerly referred to as Level 5).

Bi-Level

A key member of an homologous series has passed Full and all other members have passed Partial. The validity of this has been shown by Guild et al. ²  (formerly referred to as Level 5B).

Partial

Passive monitor has passed NIOSH protocol requirements for sampling rate, desorption efficiency, humidity effects, reverse diffusion, and storage stability test for reactive compounds. Partial validations are not recommended for compliance sampling.

Calculated

Uptake rate that is calculated from the physical properties of the analyte and geometry of the sampler. Calculated rates are not based upon direct laboratory testing of the analyte with the sampler. Calculated validations are not recommended for compliance sampling.

• 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.

Transferable Sorbent Passive Sampler
SKC introduces a 575 Series passive sampler option. The new 579 Series passive samplers are designed to allow sorbent to be transferred from the sampler housing into a standard laboratory vial for solvent extraction and analysis. This design provides convenience for laboratories using gas chromatographs with auto samplers. The sampler housing can be reused several times to reduce cost. A sorbent transfer funnel is available.

Passive Sampler for Styrene
The 575-006 Passive Sampler for styrene meets the specifications of new OSHA Method 1014. The sampler contains 500 mg of tert-butyl catechol-treated Anasorb 747 sorbent. At an uptake rate of 13.55 ml/min, the badge samples styrene for 15-minute Ceiling or 8-hour TWA sampling times (not suitable for 5-minute peak samples)
