Claim:
1. A cathodic electrochemiluminescent analytical device to determine an amount of an analyte, said device comprising a disposable assay cartridge and a time resolved luminescene measurement instrument, said essay cartridge comprising an electrode chip wherein: one or more working electrodes and one or more counter electrodes are integrated on the chip on one plane, the material of the one or more working electrodes being a conductor or strongly doped semiconductor both of which are covered by an electrical insulator layer having a thickness of 0.5 to 50 nm and the working electrodes serving as cathodes of the device, the one ore more counter electrodes being made of metal by sputtering or vacuum evaporation or other standard metalization procedures or by printing with conductive ink or dipping in an conductive ink, and the counter electrodes serving as anodes of the device, the working electrodes and the counter electrodes having contact strips to an end of the electrode chip or corners of the chip, or through the chip, by which the electrodes can be connected to excitation electronics of the luminescence measurement instrument, and wherein a sample to be analyzed is capable of giving a luminescence signal proportional to the amount of the analyte during or after applying excitation pulses of 35-65 V to the chip.
