Abstract:
1. A method for chemically separating a target constituent from a matrix, the method comprising: impregnating a microscopic pore of a section of expanded polytetrafluoroethylene (ePTFE) tubing with a binding agent, the section of ePTFE tubing comprising a single membrane having an outer surface in direct communication with an exterior environment, the section of ePTFE tubing further having a lumen for receiving at least one of a preparatory agent and a matrix; optimizing binding of the target constituent to the binding agent by treating the matrix with a preparatory agent; loading the matrix onto the microscopic pore of the section of ePTFE tubing; binding the target constituent with the binding agent; and providing a container having an opening for receiving a sample from the outer surface of the single membrane; and providing a y-adapter having a first end, a second end, and a third end, and a lumen interconnecting the first and second ends of the y-adapter, the first end of the y-adapter being coupled to a first end of the section of ePTFE tubing, the second end of the y-adapter being coupled to a second end of the section of ePTFE tubing, the section of ePTFE tubing forming a loop, and the third end of the y-adapter being configured to receive at least one of the matrix, the preparatory agent, and a stripping agent.
