Abstract

According to an aspect of the invention, an electrochemical cell for analysis of a sample is provided, comprising a dual electrode having a dielectric strip with electrical conductors on opposite sides. According to a preferred embodiment, the electrochemical cell comprises a base, and a first reagent the proximate the dual electrode. According to a further preferred embodiment, a second reagent is provided proximate the dual electrode. A cover may also be provided comprising a sample aperture. According to a particularly preferred embodiment, the first and second reagents are superposed, and the dual electrode is between the first and second reagents. The dual electrode separates the two and preserves chemical stability until a sample is applied.
