In an amplification reaction in a microfluidic apparatus, the reaction is carried out using starting substances tagged with fluorophore and quencher. The detection of reaction products occurs according to the disclosure by a separation of fluorophore and quencher occurring in the context of the amplification reaction. For the detection reaction, at least one energy-transferring substance is added and the evaluation occurs on the basis of the fluorescence emission of the fluorophores which occurs.
