1. A sample element comprising:

  • first and second substantially parallel faces separated by an intermediate member, the parallel faces and the intermediate member at least partially defining a sample chamber configured to hold a volume of fluid;

    an optical path extending through the parallel faces and the intermediate member, such that electromagnetic radiation can propagate through the sample chamber; and

    an identifying compound disposed within or on at least one of the parallel faces, the identifying compound having at least one indexed optical absorbance feature, such that spectral analysis of electromagnetic radiation propagated through the sample chamber yields the indexed optical absorbance feature;

    wherein detection of the indexed optical absorbance feature in electromagnetic radiation propagated through the sample chamber indicates to an analyte detection system whether the sample element is configured for use with the analyte detection system.
