Abstract
The ability to switch at will between amperometric measurements and potentiometric measurements provides great flexibility in performing analyses of unknowns. Apparatus and methods can provide such switching to collect data from an electrochemical cell. The cell may contain a reagent disposed to measure glucose in human blood.

155. An apparatus for use with a reaction cell having a first electrode and a second electrode, the apparatus comprising
a voltage source providing a controllable voltage to the first electrode; -
a voltage sensor sensing voltage provided to the first electrode; and an amplifier; a plurality of switches each switchable between first and second positions, wherein when said plurality of switches is in a first switch configuration the amplifier measures current through the second electrode, thereby measuring current through the reaction cell, and wherein when the switches are in a second switch configuration the amplifier permits measurement of a voltage between the first and second electrodes. - View Dependent Claims (166)
