Abstract:
1. A method of purifying a component of a sample, comprising: providing a column chamber, the column chamber having an inlet end and an outlet end, the outlet end terminating proximate both a first flow path and a second flow path, the flow paths extending through a valve having at least two positions that controls flow in the flow paths, the first flow path being obstructed with a porous retaining material permeable to a first fluid and impermeable to a matrix material, flow in the second flow path blocked when the valve is in a first of the at least 2 positions, and flow in the first flow path blocked when the valve is in a second of the at least two positions; placing the valve in the first position; flowing the first fluid and the matrix material into the column chamber and along the first flow path to form a packed column of the matrix material within the column chamber, the matrix material being configured to selectively retain a component of the sample; flowing the sample through the packed column and along the first flow path to separate the component from the rest of the sample; placing the valve in the second position; and
