Electrochemiluminescence systems consist of a bipotentiostat/galvanostat capable of producing reactions in a luminophore by applying voltage or current pulses. The state of the luminophore is detected by a cell that includes the detector (a photodiode or micro spectrometer, depending on the model). The Metrohm DropSens systems are miniaturized and portable – perfect for electrogenerated chemiluminescence (ECL) analysis.

The instruments can also be used independently as a bipotentiostat/galvanostat for electrochemical analysis with all the features of Metrohm DropSens instruments. Depending on the ECL instrument, the cells can be combined.

Electrochemical and chemiluminescence responses are perfectly synchronized and displayed in real time. Moreover, the Metrohm DropSens instruments allow good temporal and spatial control of these analytical techniques, even when the sensitivity to light signals is very low.
