Abstract
Systems and methods employing beds of bagged and caged absorbent and adsorbent materials are disclosed. These inventions are useful in the area of solid phase extraction.
Claims21
A system for extracting a substance of interest out of a liquid to form an extracted liquid and an isolated substance of interest, comprising:
- a. porous extraction material;
- b. a porous bag adapted to load and enclose the porous extraction material;
- c. a substantially rigid cage having at least two sections that sandwich and squeeze the loaded porous bag from both sides and immobilize the loaded porous bag relative to the rigid cage, yielding a rigid caged bag having substantially uniform thickness, and having a length and width being substantially larger than its greatest thickness;
- d. a mechanism coupled to the caged bag adapted to move the liquid through the caged bag to efficiently collect the substance of interest resulting in the extracted liquid and the isolated substance of interest.

A system for efficiently extracting a substance of interest out of a liquid to form an extracted liquid and an isolated substance of interest, comprising:
- a. porous extraction material;
- b. a porous bag adapted to receive and load the porous extraction material;
- c. a substantially rigid cage having at least two sections that sandwich, squeeze and immobilize the loaded porous bag from both sides relative to the rigid cage, yielding a rigid caged bag having substantially uniform thickness, and having a length and width being substantially larger than its greatest thickness;
- d. a stirring actuator adapted to move the liquid through the rigid caged bag to efficiently collect the substance of interest, resulting in the extracted liquid and the isolated substance of interest.
1 more element
A caged bag for extracting a substance of interest out of a liquid, comprising:
- a. a porous bag enclosing a porous extraction material adapted to extract substances from liquids passing through it;
- b. a substantially rigid cage that is adapted to open to receive and then close upon the porous bag with its porous extraction material;
- wherein the rigid cage sandwiches and squeezes the bag from both sides, yielding a rigid filled bag having substantially uniform thickness, the rigid cage also having a length or width at least two-fold greater than its greatest thickness, and the porous bag filled with porous extraction material is adapted to extract substances from liquids passing through it.
