Abstract
Method for fluorescence spectroscopic determination of a biological substance provided with a marker consisting of a lanthanide chelate complex formed by a lanthanide coupled to the substance via a chelate forming compound, such as an EDTA-analogue, the lanthanide ion before the detection is dissociated from the active substance for instance by adding a buffer with a pH value below 3.5 and a splitting detergent, whereafter the excitation in the determination takes place in the solution in the presence of a .beta.-diketone by using a short radiation pulse and the fluorescence from the marker is detected when the fluorescence from the noise sources has substantially ceased.
