摘要： An electrochemical sensor is described for determination of glucose in a liquid blood sample. This comprises a first sheet (14) having a palladium sputter coating, as well as a second sheet (15) having a palladium sputter coating and a third sheet of electrically resistive material having an aperture (11) extending through the third sheet and defining a side wall of the cell. The space between the first sheet and the second sheet comprises a capillary space. A ferricyanide mediator is supported on one of the coatings. Access to the cell is provided at the side edge of the cell where notches (16) extending through the first sheet, second sheet, and third sheet intersect cell (11). A liquid blood sample in contact with a notch is spontaneously drawn by capillary action into the electrochemical cell.

摘要： A method for determining the concentration of reduced (or oxidised) form of a redox species in an electrochemical cell of the kind comprising a working electrode and a counter electrode spaced from the working electrode by a predetermined distance, said method comprising the steps of: (1) applying an electric difference between the electrodes; (2) selecting the potential of the working electrode such that the rate of electro-oxidation of the reduced form (or electro-reduction of the oxidised form) of the species is diffusion controlled, (3) selecting the spacing between the working electrode and the counter electrode so that reaction products from the counter electrode arrive at the working electrode; (4) determining current as a function of time after application of the potential and prior to achievement of a steady state; (5) estimating the magnitude of the steady state current, and (6) obtaining from the change in current with time and magnitude of the steady state current, a value indicative of the diffusion coefficient and/or of the concentration of the reduced form (or the oxidised form) of the species. Also disclosed is an apparatus for determining the concentration of a redox species in an electrochemical cell comprising: an electrochemical cell having a working electrode and a counter (or counter/reference) electrode, means for applying and electric potential difference between said electrodes, means for measuring the change in current with time, and characterised in that the working electrode is spaced from the counter electrode by less than 500µm.

摘要： Methods of determining a corrected analyte concentration in view of some error source are provided herein. The methods can be utilized for the determination of various analytes and/or various sources of error. In one example, the method can be configured to determine a corrected glucose concentration in view of an extreme level of hematocrit found within the sample. In other embodiments, methods are provided for identifying various system errors and/or defects. For example, such errors can include partial-fill or double-fill situations, high track resistance, and/or sample leakage. Systems are also provided for determining a corrected analyte concentration and/or detecting some system error.
