Passive Samplers for PPM-level Organic Vapors

barrier maintains sample uptake by molecular diffusion independent
of wind velocity. The sorbent is chosen to best collect the chemical
hazards of interest.
SKC Passive Samplers
SKC passive samplers
are small samplers that 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 575 Series passive samplers along
with other critical sampling parameters to meet OSHA/ASTM/ANSI requirements.
SKC 575 Series Passive Samplers are identified as a viable alternative
to active sampling in seven OSHA methods.
- Highly accurate and reliable
Proven performers in the laboratory and in the field
- 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
- Superior collection efficiency
- SKC sorbents have a larger surface area for higher capacities
- Samplers contain >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
- So easy to use!
- No pump or training required
- Meet ASTM D6246-08 and ANSI/ISEA 104-1998(r 2009) standards
- Identified as viable alternative to active sampling
in seven OSHA methods
Full-shift Sampling with only ONE
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 sampler to get a true 8-hour TWA!
Using an SKC Passive Sampler is as easy as
1, 2, 3.
1. Remove sampler from pouch.
2. Record start time, remove cap, and attach to a worker
or at a location.
3. Stop sampling by replacing cap and record stop time.
Send the sampler to an accredited laboratory for analysis.
575 Series Passive Samplers Validated to
NIOSH Protocol 1
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.
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.
- 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).
- A key member of an homologous series has passed full validation
and all other members have passed partial. The validity of this
shown by Guild et al. 2 (formerly
referred to as Level 5B).
- 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.
- 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.
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.
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.
