RARE METALS AS COMPONENTS OF COATINGS IN DIAGNOSTIC TEST ELEMENTS AND METHODS OF DETERMINING AN AMOUNT/QUALITY OF DRIED COMPOSITIONS IN SUCH COATINGS

摘要

Coating compositions are described that include one or more rare metal components, such as rare alkali metal components, as well as diagnostics test elements that incorporate the same. Methods also are described for determining an amount of a dried coating composition in a coat based upon the rare metal components.
