5. Aft er sampling, stop the pump. Unscrew the front
plate from the housing body and remove the cassett e
from the sampler (may use sterile forceps and gloves
depending on the contaminant of interest). Place the
cover on the cassett e and wipe the external surface
of the cassett e with a clean lint-free paper, cloth,
or soft brush (may use sterile items depending on
the contaminant of interest). Place cassette with
cover into the supplied transport clip (Figure 8). For
post-weighing instructions, see Analysis on page 9. If
not performing post-weighing on the premises, see
Transporting Samples to a Laboratory on page 9.
Note: If inhalable samples were collected to
determine exposure to formaldehyde on dust using
NIOSH Method 5700, place the cassett e cover on
the cassett e and load it into the transport clip. Send
cassett e in clip, a blank, and all other pertinent
sampling information to a laboratory for analysis.
Sampling for Bioaerosols
Using MultiDust Foam Disc and Filter
Note: Use stainless steel cassett es only.
Note: MultiDust Foam Discs are designed for single use only. MultiDust Foam
Discs are pre-washed to ensure the highest quality and accurate results. Use only
MultiDust Foam Discs with the IOM.
Filters, foam discs, and cassett e must be sterilized and handled
aseptically. See Preparation and Assembly on page 3.
1. Sterilize stainless steel cassett e, fi lter, and foam disc. A 25-mm polycarbonate fi lter
is recommended. See Sterilizing Filter, Foam, and Cassett e (for Bioaerosol Sampling)
on page 3.
2. Load fi lter into cassett e. See Filter Cassett e: Opening, Installing Filter, and Closing,
page 4.
3. Place the MultiDust Foam Disc for respirable (Cat. No. 225-772) into the inlet
of the cassett e top so that it sits just below the rim (Figure 7). Ensure the foam
is not creased and there are no gaps between the foam and the cassett e wall.
Note: The foam disc is larger than the inlet; therefore, it must be compressed
evenly to fi t properly.
4. Insert the cassett e top containing the foam disc into the cassett e bott om ensuring
the fi lter is in place. See Filter Cassett e: Opening, Installing Filter, and Closing,
page 4.
5. Calibrate the sample pump using representative sample media. See Calibration
on page 6.
6. Sample using the procedure in Sampling on page 7.
7. If shipping samples to a laboratory for analysis, see Transporting Samples to a
Laboratory on page 9. If performing analysis on the premises, see Analysis on
page 9.
