Open the CIPO recordAbstract From the Canadian patent
A sensor system, device, and methods for determining the concentration of an analyte in a sample is described. Gated amperometric pulse sequences including multiple duty cycles of sequential excitations and relaxations may provide a shorter analysis time and/or improve the accuracy and/or precision of the analysis. The disclosed gated amperometric pulse sequences may reduce analysis errors arising from the hematocrit effect variance in cap-gap volumes, non-steady-state conditions mediator background, under-fill, temperature changes in the sample and a single set of calibration constants.
