Abstract
An analytical element for the detection of two or more analytes in an aqueous liquid. The element contains an essentially dry matrix, at least a portion of the matrix containing at least two interactive compositions, a first composition generating a first radiometrically detectable species corresponding to the presence and/or concentration of one analyte, and a second composition for the inhibition or the destruction of a second radiometrically detectable species corresponding to the presence and/or concentration of one of the other analytes. The first and second interactive compositions are positioned in the element matrix to be in liquid contact with one another. Each of the first and second detectable species produced in the element is selected to have a different, characteristic, detectable absorption or emission peak in the electromagnetic spectrum.
