1. A measuring assembly comprising at least one radiation source, at least one detector and a supporting element being transparent to excitation and measurement radiation and having first, second and third boundary faces, said supporting element being provided with several luminescence-optical sensor elements on said first boundary face, and picks up excitation radiation from said radiation source via said second boundary face, and supplies measurement radiation of said sensor elements to said detector of an evaluation unit via said third boundary face, the direction of said excitation radiation being essentially normal to the direction of detection, and the refractive index n1 of said supporting element being greater than the refractive index of the environment, wherein said several sensor elements are connected by a common sample channel, and wherein means are provided for optical or temporal separation of light paths of said measurement radiation emitted by said individual sensor elements.
