  • Method for determining the concentration of a fluorescent and/or fluorescence-labeled analyte, and calibration method for preparing such determination
    Patent number: 11255784
    Abstract: A method for determining the concentration of a fluorescent and/or fluorescence-labeled analyte, and to a calibration method for preparing such determination, for use in the field of biological and environmental analysis in order to improve the accuracy of concentration determination, comprising the following steps: performing fluorescence measurements for calibration samples that have predetermined concentrations of a plurality of fluorescent and/or fluorescence-labeled reference analytes Rj that differ from each other by values m of a diffusion measure characterizing the diffusion of the reference analyte, in order to determine the values i of a concentration-dependent parameter I; establishing functions Fj(c)=i which describe the dependence of the parameter I on the concentration; determining the values of a slope parameter a for the respective reference analyte as a derivative of the respective function at c=0; determining the values mj of the diffusion measure for the reference analytes; establishing the
