Instruction Manual

5. A er sampling, stop the pump. Unscrew the front

plate from the housing body and remove the casse e

from the sampler (may use sterile forceps and gloves

depending on the contaminant of interest). Place the

cover on the casse e and wipe the external surface

of the casse e with a clean lint-free paper, cloth,

or so 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 casse e cover on

the casse e and load it into the transport clip. Send

casse 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 casse 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 casse e must be sterilized and handled

aseptically. See Preparation and Assembly on page 3.

1. Sterilize stainless steel casse e, ﬁ lter, and foam disc. A 25-mm polycarbonate ﬁ lter

is recommended. See Sterilizing Filter, Foam, and Casse e (for Bioaerosol Sampling)

on page 3.

2. Load ﬁ lter into casse e. See Filter Casse 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 casse 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 casse e wall.

Note: The foam disc is larger than the inlet; therefore, it must be compressed

evenly to ﬁ t properly.

4. Insert the casse e top containing the foam disc into the casse e bo om ensuring

the ﬁ lter is in place. See Filter Casse 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.
