SKC Abrasive Blasting Sampler
For Heavy Metals
- 4 L/min flow rate enhances sensitivity
- Withstands mechanical stress during blasting
- Low sensitivity to wind direction and velocity
- Prevents filter damage from rebound particles
- Reduces electrostatic effects
- Small and lightweight
- Uses most 25-mm filter materials
- Reduces over sampling of very large particles
- Provides equal distribution of particle loading and low intersample variation
- Protects filter from overloading by large particles thrust onto the sample
- Follows closely the ACGIH/ISO sampling criteria for inhalable particulate mass
- Suitable for collecting bioaerosols for viable or non-viable analysis

SKC Abrasive Blasting Sampler for Heavy Metals
SKC has combined the sampling efficiency of the patented Button
Sampler for inhalable dust with the protection of a specially designed shield
to create
the SKC Abrasive Blasting Sampler for Heavy Metals. The reusable SKC Button
Aerosol Sampler is a filter sampler with a porous curved-surface inlet designed
to improve the collection characteristics of inhalable dust (< 100 µm
aerodynamic diameter), including bioaerosols for total non-viable or viable
microbial count. The conductive stainless steel inlet reduces electrostatic
effects and contains evenly spaced holes that act as sampling orifices for
multi-directional sampling capability and low sensitivity to ambient air effects.
When combined with the protective shield, the Button Sampler becomes an efficient
sampler for heavy metals in abrasive blasting environments *.

The SKC Abrasive Blasting Sampler for Heavy Metals is not suitable for
sampling silica. Silica is commonly found in abrasive blasting. However,
sampling for silica using OSHA Method ID 142 requires a cyclone. |
Sampler Proven Effective in Abrasive Blasting Environments
The SKC Abrasive Blasting Sampler for Heavy Metals has been used to monitor
the personal exposure of workers performing abrasive blasting at four U.S.
Military facilities. The
sampler reliably withstood blasting operations that included very high particle
concentrations containing metals such as lead, cadmium, and chromium. The sampler
provided recoverable samples and meaningful exposure information.
Performance Profile
| Flow Rate: |
| |
4 L/min
The Button Sampler closely follows the ACGIH/ISO inhalability curve at
4 L/min. This provides optimum sampling. Sampling efficiency is maintained
within ± 30% at flows ranging from 2 to 5 L/min. |

Abrasive Blasting Sampler Operation

The SKC Abrasive Blasting Sampler for Heavy Metals is easy to operate. Simply
load the conditioned and weighed 25-mm filter into the sampler, reassemble
it, push the shield into place over top of the inlet, and clip it to a worker's
collar.
Connect
the
sampler
to a sample pump capable of 4 L/min
for personal exposure sampling following the ACGIH/ISO inhalable criteria.
The pump can be clipped to the worker's belt. The sampler shows the same sampling
efficiency standing freely as it does attached to a worker.

Button Sampler Calibration Adapter
The Button Sampler Calibration Adapter is designed specifically for
use with the Button Sampler and is easy to use. Simply place adapter
onto sampler inlet, connect adapter inlet to a calibrator, and connect
the Button Sampler outlet to a pump. Calibrate sample pump to the desired
flow rate. Following calibration, remove adapter, press abrasive blasting
shield onto Button Sampler inlet, and sample.
Note: It is not necessary to calibrate pump with
shield in place, it does not affect flow rate.
