Abstract
The invention concerns methods and apparatuses for quantitatively determining the concentration of fluorophores of a substance in a sample. A constant portion of the reference light of a reference light wave length (λ) emitted by a reference light source is coupled in by an optical element in the direction of a receiving element. A first value corresponding to the portion of the reference light coupled in which is incident on the receiving element is detected. The sample is irradiated with the excitation light of an excitation wave length (λ) emitted by an excitation light source. A second value corresponding to the portion of the fluorescent light of an emission wave length (λ) emitted by the sample which is incident on the receiving element. The ratio of the second value to the first value is determined. The number of fluorophores in the substance is determined based on the ratio.
