Abstract

A method for on-line monitoring of test sensors using XRF spectrometry including providing a test sensor. The test sensor comprises a reagent that includes an enzyme and a mediator. The mediator for example ferricyanide includes a metallic element for example iron. The reagent of the test sensor is monitored using XRF spectrometry.
