Solvent extraction in continuous flow systems with ...

Abstract A 50 to 100-μl segment of an extractant is injected into a flowing sample stream, to which reagents, as necessary, have been added. Following an extraction conduit typically providing a residence time of 1–3 min, the extractant segment is isolated as it flows through the loop of an injection valve. The actuation of this valve is controlled by sensing its loop-filling status with ...
