Product Usage Instructions

  1. Remove the sampler from the sealed pouch. Do not discard the pouch as it is used to protect the sampler during shipment.
  2. Write the date, start time, and sampler ID number (found on the sampler) on the label on the pouch.
  3. Remove the cap on the front of the sampler and set aside. Do NOT remove the plastic plug on the back of the sampler. Removing this plug will VOID the sample.
  4. Clip the sampler to the worker’s clothing in the breathing zone. Ensure small holes are facing out. Ensure holes are not covered in any way. Do not be exposed to excessive heat or moisture.
  5. At the end of the desired sampling period, unclip the sampler from the worker’s clothing. Replace the cap on the front of the sampler.

Sampling

Select the passive sampler with the sorbent best suited for the chemical analysis of interest. Visit www.skcinc.com and click on Sampling Guides to determine the recommended sampler for a specific compound.

  1. Remove the sampler from the sealed pouch. Do not discard the pouch as it is used to protect the sampler during shipment.
  2. Write the date, start time, and sampler ID number (found on the sampler) on the label on the pouch.
  3. Remove the cap on the front of the sampler and set aside. Do NOT remove the plastic plug on the back of the sampler. Removing this plug will VOID the sample. Clip the sampler to the worker’s clothing in the breathing zone. Ensure small holes are facing out. Ensure holes are not covered in any way. Do not be exposed to rain/spray or splashing chemicals. Do not handle with dirty fingers/gloves.
  4. At the end of the desired sampling period, unclip the sampler from the worker’s clothing. Replace the cap on the front of the sampler.
  5. Write the stop time on the label on the pouch. Important: Measure and record ambient temperature and atmospheric pressure. Include in information sent to the laboratory.
  6. Carefully package the sampler in the pouch and send it, blanks, and pertinent information to an AIHA-accredited laboratory for analysis.

Analysis

Note:
See the Ordering Information below for sorbent tubes for desorption efficiency studies.

Desorption

  1. Take out a small plug from the back of the sampler and remove the foam disc with a pair of tweezers. Transfer sorbent to vial. Tap the sampler lightly to get all sorbent particles out of the sampler.
  2. Add 2 mls of the recommended desorption solvent* to the vial.
  3. Cap vial with a PTFE-lined cap.

Go to www.skcinc.com/samplingguide/passive for desorption solvents, times, and efficiency data.

Calculations

  • C = (SW) (24.45 x 106 C = )/(DE) (MW) (SR) (MIN) (PT)

Where:

  • C = Concentration of chemical (ppm)
  • SW = Sample weight by analysis (mg)
  • PT = Pressure/temperature correction (see right)
  • DE = Desorption efficiency (see right)
  • MW = Molecular weight of chemical
  • SR = Sampling rate (ml/min)
  • MIN = Sampling time (minutes)

The equation opposite is correct for 25 C (298 K) and standard atmospheric pressure (760 mm Hg). To convert to other temperatures and pressures, the correction factor is:

  • PT = (T1/T2) 1.5 (P2/P1)

Where:

  • T1 = Sampling site temperature (in kelvin)
  • T2 = 298 K
  • P1 = Sampling site pressure (in mm Hg)
  • P2 = 760 mm Hg

Desorption efficiency should be determined and expressed as a decimal (e.g., 98% = 0.98).

Example: Sampling toluene at 38 C and 695 mm Hg

  • (3.03 mg) (24.45 x 10×6)/(0.99) (92.14) (14.5) (480) (1.166) = 100 ppm

The 575 Series diffusive samplers have been validated for specific compounds according to specific methods. Substituting a solvent other than that stated in these methods or other modifications of these methods may result in inaccurate results.
