摘要： 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.
摘要翻译：土壤取样器包括用于接收土壤样品的流化床。流化床可以与用于抽吸空气通过流化床并将土壤样品的颗粒物质悬浮在空气中的真空连通。在采样方法中，空气可以被抽过滤器，分离颗粒物质。任选地，挡板或旋流器可以包括在流化床内用于去除或除尘，因此只有最细微的颗粒物质（包括石棉）将被捕获在过滤器上。过滤器可以是可去除的，并且可以被测试以确定土壤样品中的石棉和其它有害颗粒物质的含量。
