SKC Abrasive Blasting Sampler

Versatile, Efficient, Inhalable Sampler

Withstands mechanical stress during blasting Low sensitivity to ambient air conditions Prevents filter damage from rebound particles Reduces electrostatic effects Minimal orientation effects Small and lightweight Uses most 25 mm filter materials Reduces sampling of very large particles (>100 µm) Provides superior filter collection uniformity with low intersample variation Protects filter from overloading by large particles thrust onto the sample

Abrasive Blasting Sampler: BUTTON Sampler and Protective Shield Sample Time: Varies Sampling Rate: 4 L/min optimum Sample Pump: XR Series Sample Media: 25-mm Filters

Follows closely the ACGIH/ISO sampling criteria for inhalable particulate mass Suitable for collecting bioaerosols for total viable plus non-viable microbial count

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 plus 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 *.

†	Patent Nos. 5,954,845 and 5,958,111
*	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 Range:
	2 to 10 L/min; 4 L/min is recommended
Construction:
	Sampling inlet:	conductive stainless steel
	Body:	aluminum
	Support screen:	stainless steel
Filter:
	25 mm

Abrasive Blasting Sampler Operation

The SKC Abrasive Blasting Sampler for Heavy Metals is easy to operate. Simply load the 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 2 to 10 L/min flow rate (4 L/min is recommended) 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.

Description			Cat. No.
Abrasive Blasting Kit includes Button Sampler and protective shield			225-367
Accessories			Cat. No.
Protective Shield for abrasive blasting environments			225-366
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.			225-361
