Patent ID: 8470604

Claim:
A method for determining an analyte concentration in a sample, comprising: reacting an analyte in a sample with an ionizing agent; forming a measurable species from the reaction between the sample and the ionizing agent during an incubation period from 0.1 to 8 seconds, where the measurable species concentration in the sample is responsive to an analyte concentration in the sample; applying an input signal to the sample after the incubation period, where the input signal includes excitations and relaxations, where at least two of the excitations have a duration from 0.1 to 5 seconds, and where at least one of the relaxations has a duration from 0.4 to 1 second; generating an output signal from the excitation following the at least one of the relaxations having the duration from 0.4 to 1 second, the output signal having a transient decay responsive to a redox reaction of the measurable species; and determining the analyte concentration of the sample from the transient decay of the generated output signal.
