First Claim
Patent Images
1. An analytical element comprising:
- a first reagent system for detecting an analyte, andan on-board control comprising a second reagent system that produces a signal independent of the presence of the analyte and comprises an organic N-oxide or a nitroso compound and a reducing agent.

Abstract
The invention concerns a reagent system for the so-called on-board control of analytical elements, in particular test strips, containing an organic N-oxide or a nitroso compound. The invention also concerns analytical elements containing a reagent system for a detection reaction and a reagent system for an on-board control. Furthermore, the invention concerns a method for checking analytical elements in which a reagent system for an on-board control is examined optically or electrochemically with the aid of a measuring instrument for changes which could indicate a stress of the analytical element.
