OPTICAL DETECTION APPARATUS FOR CHEMICAL ANALYSES OF SMALL VOLUMES OF SAMPLES

摘要

Optical detection apparatus for chemical analyses of small volumes of samples with light sources (21) to emit induction light, a measuring cell (7) for the sample, phoelectric sensing elements (22) to receive light coming from the sample in the measuring cell (7), as well as beam-conducting means for the induction light or the light from the sample. In the apparatus, several essentially planar, laminar components (2-7) are arranged in a sandwich structure, whereby the components (2-7) contain the light sources (21), the measuring cell (7), the photoelectric sensing elements (22), and also the beam-conducting means.
