Abstract
An apparatus for extracting at least one selected component from a substrate material, or sample is provided. The apparatus includes a separate first container that is configured to hold an extractant fluid, and a separate second container that is configured to receive at least a portion of this extractant fluid. The apparatus also includes a separate third container that is interposable between the first container and the second container and is configured to contain the substrate material. The apparatus further includes a coupling for joining the third container between the first container and the second container to form an assembly to permit fluid communication between the first container and the second container through the third container, whereby the extractant fluid is permitted to flow from the first container, through the third container and contained substrate material to collect a portion of the selected component of the substrate material, and into the second container.
