The configuration comprises a monochromatic radiation source (1), a cuvette (3) containing a solution of the substance to be studied, and a photoelectric cell (5) acting as a radiation detector. The radiation source (1) used according to the invention is at least one light-emitting diode (LED). The cost-efficient measuring configuration is notable for its compact form and its long useful life, and is particularly suitable for use in chemical and medical analysis as well as for measurements in biotechnology. <IMAGE>
