Vorrichtung zur Durchführung von Nukleinsäure-Amplifikationsreaktionen bei gleichzeitiger Verfolgung der Bildung von Amplifikationsprodukten

摘要

The invention relates to a device for photometric measurement of several samples (12) which are exposed to radiation from a light source (14) associated therewith. The light modified by the samples (12) is intercepted by an optical device (19) and is guided as a sum of all the light radiated from all samples (12) to at least one sensor (27) for measuring the intensity and evaluation thereof in an evaluation device (32) arranged downstream. The light sources (14) are controlled individually by a control device (31) and the evaluation device (32) and the control device (31) are controlled in such a way that the evaluating device (32) separates the light from each sample (12) from the light of the other samples. The invention is characterised in that the control device (31) modulates the light source (14) with various signals which are pre-assigned to the evaluation device (32) and used to determine the light signals of the individual samples (12) from the sum signal received by the sensor (27).
