  • Continuous ion species removal device and method
    Patent number: 7582482
    Abstract: Apparatus and method for treating a liquid sample stream including at least one analyte ion species and matrix ion species of opposite charge to said one analyte ion species. The liquid sample stream flows through a treatment channel. A carrier liquid stream including a matrix ion species capture material flows substantially parallel to the sample stream in the treatment channel forms a liquid interface between them. The matrix ion species diffuses through the interface to contact and become bound by the capture material in said carrier liquid.
    Type: Grant
