SKC 575 Series Passive Samplers
for Organic Vapors
SKC 575 Series Passive Samplers are small ready-to-use samplers that provide superior collection of organic vapors without the use of a sample pump. SKC has scientifi cally validated the sampling rates for many chemicals and other critical sampling parameters of the 575 Series Passive Samplers to meet OSHA/ASTM/ ANSI requirements. SKC 575 Series Passive Samplers have been identifi ed as a viable alternative to active sampling in six OSHA methods.
Performance Profi le
Sorbent/Amount: 575-001: Charcoal, 350 mg 575-002: Anasorb 575-003: Anasorb 727, 300 mg
Housing material: Nylon Diameter: 1.4 in (3.5 cm) Length
(including clip): 2.5 in (6.3 cm) Depth: 0.6 in (1.5 cm) Concentration range: Varies - dependent upon chemical of interest Analysis: Solvent desorption, Gas Chromatography/Flame Ionization
Detector (GC/FID)
Shelf-life: 2 years at < 39.2 F (4 C) Storage: Before use: Store at ambient temperature. For low-level
measurements, SKC recommends storage at < 39.2 F (4 C).
A er use: For sample storage information, refer to the
method for the chemical of interest. Expedited shipping is recommended. See Storage.
Sample time: Validated for 15-min and 8-hr occupational exposure sampling.
Lab and fi eld studies conducted with several compounds show suitability for 24-hr air sampling.
Sampling rate: Dependent upon chemical of interest. For compound-specifi c

Select the passive sampler with the sorbent best suited for the chemical of interest. Visit www.skcinc.com and click on Sampling Guides to determine the
recommended sampler for a specifi c compound.
1. Remove sampler from sealed pouch. Retain and set aside all other parts, including the desorption effi ciency tube(s).
2. Write the start time, date, and a user-assigned sampler ID number on the label on the back of the sampler. On a sheet of paper, record the temperature and atmospheric pressure at the sampling site.
3. Remove the lock, cap, and O-ring from the sampler and set aside. Clip sampler to worker’s clothing in the breathing zone. Ensure small holes are facing out.
Note: Sample the entire workshi to obtain a true 8-hour exposure. If breaks/lunch are part of the 8-hour workday or occur in the work area, samplers may remain sampling. If desired, the sampler can be removed for breaks/lunch and sealed with the provided cap. When the worker returns to the work area, replace the sampler on the worker’s clothing and remove the cap. Note the times the sampler is removed from and placed back on the worker to ensure accurate air volumes.
4. At the end of the desired sampling period, unclip the sampler from worker clothing. Push the O-ring, cap, and lock (removed during Step
3) onto the side of the sampler containing the holes.
5. Write the stop time on the label on the back of the sampler.
6. Carefully package and send the sampler, all other parts, and sampling site information including temperature and atmospheric pressure to an AIHA-accredited laboratory for analysis. If using an in-house laboratory, refer to the analysis instructions included in this package.

Validation
SKC 575 Series Passive Samplers for organic vapors have been validated to the rigorous NIOSH and ANSI testing protocols.
Full - Passed all NIOSH Partial validation protocol and factorial study, including interfering compounds; most rigorous test; includes all parameters aff ecting sampling accuracy
Bi-level - A key member of a homologous series passed Full validation, all others passed Partial. Validity shown by Guild et. al. (see References).
Partial - Passed NIOSH protocol for sampling rate, desorption effi ciency, humidity eff ects, reverse diff usion, and storage stability (reactive compounds).
Calculated - Uptake Rate - D x (A/L). “D” is a diff usion coeffi cient calculated from the Hierschfelder Equation. “A/L” is a constant based on the geometry of the sampler.
For compliance sampling, it is recommended that only those passive samplers with agency, Full, or Bi-level validation be used. Passive samplers with lower validation levels should be used only if verifi ed by sorbent tube methods.
