ABSTRACT:
A method for rapid and sensitive membrane assisted Flow Injection Analysis. A sample, containing a component to be analyzed, is injected into a flowing stream of carrier liquid and flowed past one side of a two-sided membrane. A receiving liquid is flowed past the other side of the membrane. The component to be analyzed is absorbed by the membrane from the carrier stream, is desorbed into the receiving stream and is carried to a detector for analysis in less than about 5 minutes. Critically, the partition coefficient of the component to be analyzed between the membrane and the receiving liquid is less than about 1.times.10.sup.1.
