Abstract
A disposable integrated miniaturized array of chemical sensors for analyzing concurrently a number of analytes in a fluid sample is described. Each sensor is a complete electrochemical cell consisting of its own individual reference and indicator electrodes and is selective with respect to a particular analyte in the sample. Where required, a sensor can be individually calibrated, such that each analysis can be read directly.
Claims5
An article of manufacture used for analyzing a multiplicity of analytes in a fluid sample, said article comprising an array of discrete, electrically isolated electrochemical sensors supported on a common substrate for analyzing different ones of said analytes, at least one of said sensors in said array having a built in calibrating means including means to establish a differential concentration of an analyte within said one sensor during measurement comprising, a first electrode layer containing a given concentration of the analyte being measured, and a second electrode layer containing a given but different concentration of the analyte being measured, and electrical means to provide access to each of said sensors.
