Soil Separator and Sampler and Method of Sampling

Fluidized Bed system

Idaho National Laboratory

Contact INL About This Technology

Technology Marketing Summary

INL has developed a method for sampling soil to determine the presence of extremely fine particles such as asbestos.

Description

The apparatus uses a fluidized bed for receiving a soil sample, which is connected to a vacuum for drawing air through the bed and suspends particulate matter of the soil sample in the air, and draws air across a filter, which separates the particulate matter. Optionally, a baffle or a cyclone can be included within the fluidized bed for distrainment, or de-dusting, so only the finest particulate matter reaches the filter. The apparatus has been used for sampling / quantifying asbestos contamination and other hazardous particles found in soil.

Benefits

-        Takes extremely fine particle samples, and

-        Detects and separates asbestos and other hazardous particles

Applications and Industries

Soil sample, dirt/soil testing, asbestos hazard analysis

Soil separator and sampler and method of sampling
A soil sampler includes a fluidized bed for receiving a soil sample. The fluidized bed may be in communication with a vacuum for drawing air through the fluidized bed and suspending particulate matter of the soil sample in the air. In a method of sampling, the air may be drawn across a filter, separating the particulate matter. Optionally, a baffle or a cyclone may be included within the fluidized bed for disentrainment, or dedusting, so only the finest particulate matter, including asbestos, will be trapped on the filter. The filter may be removable, and may be tested to determine the content of asbestos and other hazardous particulate matter in the soil sample.
