摘要： Methods and apparatus for electrochemically determining an analyte concentration value in a physiological sample are disclosed. The methods include using a test strip in which two time-current transients are measured by a meter electrically connected to an electrochemical test strip. Integrative current values are derived from the time-current transients and used in the calculation of analyte concentration.

摘要： The present invention relates to a device and method for measuring the level of an oxidant or antioxidant analyte in a fluid sample. The device comprises a disposable electrochemical cell, such as a thin layer electrochemical cell 1, containing a reagent capable of undergoing a redox reaction with the analyte. When the device 1 or method is to be used with slow-reacting analytes, heat may be applied to the sample by a resistive heating element in the device 1 or by an exothermic material contained within the electrochemical cell 8. Application of heat accelerates the rate of the redox reaction between the reagent and the analyte and thus facilitates the electrochemical measurement of slow-reacting analytes.

摘要： The present invention relates to the measurement of the progress of a chemical reaction that generates an electroactive reaction product that is subsequently detected at an electrode amperometrically or coulometrically. The method is useful in applications where it is desirable to follow the progress of a chemical reaction, particularly in sensor applications where the progress of the reaction of an analyte can be useful in determining the analyte concentration. Sensors used in such applications may include a working electrode (2) and a counter electrode (3) disposed on an electrically insulating substrate (1), and may also include a second substrate (5) upon which is disposed a layer of chemical reactants (4).

摘要： The present invention relates to electrochemical cells including a first working electrode 32, a first counter electrode 34, a second working electrode 36, and a second counter electrode 38, wherein the electrodes are spaced such that reaction products from the first counter electrode 34 arrive at the first working electrode 32, and reaction products from the first and second counter electrodes 34, 38 do not reach the second working electrode 36. Also provided is a method of using such electrochemical cells for determining the concentration of a reduced or oxidized form of a redox species with greater accuracy than can be obtained using an electrochemical cell having a single working and counter electrode.
