Manual

4. For area sampling, position the Bu on Sampler to avoid cross-dra s and

direct projection of the particles into the inlet.

5. At the end of the sampling period, stop the pump and record the stop time.

Sample Shipment

1. When sampling is complete, very gently unscrew the sampler inlet and use

forceps to remove the PTFE O-ring.

2. Using forceps, carefully remove the ﬁ lter from the sampler.

3. Package for shipment as directed by the method or laboratory.

4. Ship samples with pertinent sampling information to an accredited laboratory

for analysis.

Analysis

Dependent upon the hazard of interest, samples taken with the Bu on Sampler

can be analyzed using gravimetric analysis, analytical techniques such as x-ray

ﬂ uorescence, atomic absorption (AA), or inductively coupled plasma (ICP).

Growth culture, microscopy, and other assays may be used for the determination

of fungal spores, endotoxin, and bacteria.

If gravimetric analysis is used, weigh the ﬁ lter and subtract the preweight from the

postweight. The net weight will be the dust collected.

Using the Button Sampler as an Abrasive Blasting

Sampler for Heavy Metals

‡

SKC has designed a protective shield for the Bu on Sampler for use when sampling

in abrasive blasting environments. The shield protects the ﬁ lter from shredding

or being overloaded by large particles thrust onto the sampler during

blasting. Tested by the U.S. Military during recent abrasive blasting operations, the

Bu on Sampler with protective shield (Abrasive Blasting Sampler for Heavy

Metals) withstood very high particle concentrations and provided recoverable

samples and meaningful exposure information. The shield is very easy to use,

simply push it onto the sampler inlet and sample (see Sampling).

‡ The Bu on Sampler with shield is not suitable for sampling silica. While silica is commonly found in

abrasive blasting environments, sampling for silica using OSHA Method ID 142 requires a cyclone.

Using the Button Sampler to collect Inhalable

Bioaerosols

The patented SKC Bu on Aerosol Sampler provides superior collection of

inhalable particles including bacteria and fungal spores. Use the Bu on Sampler

with a 25-mm membrane ﬁ lter such as MCE or PVC to collect bioaerosols for

viable or non-viable analysis. Using SKC gelatin ﬁ lters with the Bu on Sampler

increases the survival of stress-sensitive microorganisms during sampling. The

Bu on Sampler is used with a sample pump capable of 4 L/min for personal

inhalable particulate sampling following the ACGIH/ISO criteria.

Note: Gelatin ﬁ lters dissolve when placed on agar.
