SYSTEMS AND METHODS FOR IMPROVED STABILITY OF ELECTROCHEMICAL SENSORS

摘要

Methods for determining a concentration of an analyte in a sample, and the devices and systems used in conjunction with the same, are provided herein. In one exemplary embodiment of a method for determining a concentration of an analyte in a sample, a sample including an analyte is provided in a sample analyzing device having a working and a counter electrode. An electric potential is applied between the electrodes and a measurement of a parameter correlating to changes in a physical property of the sample analyzing device is calculated. A concentration of the analyte in view of the parameter correlating to a change in the physical property can then be determined. Systems and devices that take advantage of the parameter correlating to changes in a physical property to make analyte concentration determinations are also provided.

1. An electrochemical system, comprising:
an electrochemical cell having a first electrode and a second electrode; a meter including a control unit connected to the electrochemical cell so that the control unit applies a potential between the first electrode and the second electrode of the electrochemical cell and the control unit determines a measurement of a parameter correlating to a physical property of the electrochemical cell and uses said measurement to calculate a corrected concentration of the analyte in the sample.
