Abstract

The invention relates to a method and a device for the recording of process parameters of reaction fluids in several microreactors which are continuously agitated, at least until the termination of the reaction in all the microreactors. The process parameters in the microreactor are recorded during the reaction by means of at least one sensor optical system. According to the invention, the reliability of the method may be increased, whereby, during the recording of the value of a process parameter, for example, on recording an instantaneous value of the auto-fluorescence of the reaction fluids, the sensor optical system is held stationary. The relative movement of the agitated microreactor and each sensor optical system thus produced is not problematical when the electromagnetic radiation from each sensor optical system is introduced exclusively into one of the microreactors concerned during the recording of the process parameter in said microreactor and the radiation emitted from the reaction fluid is only incident on the sensor of the corresponding sensor optical system.
