Abstract
The present invention relates to a dry control cartridge for providing a plurality of voltage and impedance inputs to an electrochemical analysis instrument for verification of its proper functioning. The dry control cartridge includes a battery and a plurality of electrical circuits for providing a plurality of predetermined voltage and impedance outputs. The dry control cartridge is adapted for insertion into an electrochemical analysis device using probe electrodes to measure microvolt-range potential differences, appropriate to the input ranges inherent in the instrument. By comparing the measured voltage and impedance inputs to the predetermined outputs of the cartridge, verification of the instrument's proper functioning and accuracy may be made.
