Method and apparatus for analyte measurement including real-time quality assessment and improvement

Abstract

A method of analyzing a material () comprising at least one analyte, wherein analyte-wavelength-specific measurements are interspersed with reference measurements (), and wherein response signals obtained for the reference measurements () are used for one or more of calibrating an excitation radiation source () for generating said excitation radiation, calibrating said detection device, recognizing a variation in the measurement conditions by comparing results of individual reference measurements (), adapting the analyte measurement procedure () with respect to one or more of the entire duration thereof, the absolute or relative duration of analyte-wavelength-specific measurements for a given analyte-characteristic-wavelength, or terminating and/or restarting the analyte measurement procedure, and adapting the analysis carried out in the analyzing step.
