ABSTRACT:
A method and apparatus for removing concentrated spots of collected particulates from an impact collection surface, and transferring those particulates into a container suitable for preparing a liquid sample. A jet of fluid can be utilized to remove and transfer the particulates. If a liquid jet is employed, care is taken to minimize the quantity of liquid to avoid unnecessarily diluting the sample. A mechanical scraper can alternatively be employed to remove and transfer the particulates into the container. The scraper can be rinsed with liquid or vibrated to remove the particulates. Alternatively, the portion of the surface containing a specific spot of particulates can be removed and placed into a container.
