  • Method and device for measuring process parameters in liquid cultures
    Patent number: 11635381
    Abstract: A method for measuring process parameters in liquid cultures in a plurality of microreactors of at least one microtiter plate includes continuously agitating the liquid cultures using an orbital agitator at least until the reaction is completed in all the microreactors. In order to allow process parameters also of such substances which themselves do not have any fluorescence activity to be measured with relatively low complexity and within a short time, 2D fluorescence spectra are recorded in a plurality of in particular different liquid cultures in the microreactors of agitated microplates. A device for carrying out the method is also disclosed.
