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

sampling rates, visit www.skcinc.com and click on Sampling Guides.

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.
