Claim Text:
1. A method for measuring the concentration of an analyte in a sample, comprising: (a) for each of a plurality of concentrations of the analyte: (b) generating a curve of the peak variances from step (a) by plotting the peak variances against their respective analyte concentrations, thereby generating a standard curve; (c) flowing the analyte from the sample in the presence of the concentration of the ligand under pressure through the narrow tube, capillary, or channel, wherein the flowing satisfies conditions of Taylor dispersion; (d) measuring the flow induced dispersion of the ligand by detecting a UV or fluorescence signal generated by the ligand of step (c) with the detector; (e) calculating a variance of a peak of the signal from step (d); and (f) comparing the variance from step (e) to the standard curve, wherein the closest match between the variance from step (e) and a point on the standard curve determines the concentration of the analyte in the sample.
