1. A method of determining an analyte concentration, comprising:

  • applying at least one first pulse at a first potential and at least one second pulse at a second potential to a sample solution containing an analyte, wherein the first potential and the second potential are the same polarity and the second potential is larger than the first potential;

    measuring at least one first current-transient associated with the at least one first pulse and at least one second current-transient associated with the at least one second pulse;

    determining a ratio between at least one said first current-transient and at least one said second current-transient, wherein said current-transients are measured at a substantially common sampling-time; and

    determining an analyte concentration of the sample solution based on the ratio of said current-transients.
