ABSTRACT:
A method of operating an analytical flow cell device comprising an elongate flow cell having a first end and a second end, at least two ports at the first end and at least one port at the second end, comprises introducing a laminar flow of a first fluid at the first end of the flow cell, and a laminar counter flow of a second fluid at the second end. Each fluid flow is discharged at the first end or the second end, and the position of the interface between the first and second fluids in the longitudinal direction of the flow cell is adjusted by controlling the relative flow rates of the first and second fluids. Also disclosed are a method of analyzing a fluid sample for an analyte, a method of sensitizing a sensing surface, and a method of contacting a sensing surface with a test fluid.
