Abstract: An object of the present invention is to provide an organic electroluminescent element containing: a plurality of light emitting units interposed between a pair of an anode and a cathode; and a charge generating unit formed between the light emitting units, wherein a light emitting layer of a light emitting unit located in an N-th order from the anode and a light emitting layer of a light emitting unit located in an (N+1)-th order from the anode each contain an emission dopant to emit light of the same emission color; and a largest maximum emission wavelength in a photoluminescent spectrum of the emission dopant in the light emitting layer of the N-th light emitting unit is shorter than a largest maximum emission wavelength in a photoluminescent spectrum of the emission dopant in the light emitting layer of the (N+1)-th light emitting unit.

Abstract: An analysis system, a learned model generation device, a discrimination system, an analysis method, a learned model generation method, and a discrimination method can sensitively quantify at least one of an aggregation state or a surface state. An analysis system includes an acquisition unit for acquiring a signal change over time due to interaction between a capture target substance and a capture substance by an electrical detection method or optical detection method, and an analysis unit for analyzing at least one of an aggregation state and a surface state of the capture target substance from the signal change over time acquired by the acquisition unit.
