Beschreibung
Zusammenfassung:	Described is an electrochemiluminescence method of detecting an analyte in a liquid sample using a measuring cell having a working electrode for detecting the analyte using an electrochemiluminescence measurement cycle, involvinga. carrying out the measurement cycle in a calibration process using a liquid sample without analyte and performing a first electrochemical impedance spectroscopy, EIS, at a given point of the measurement cycle, the first EIS being performed using the working electrode,b. carrying out the measurement cycle in an analysis process using the liquid sample containing the analyte and performing a second EIS at the given point of the measurement cycle, the second EIS being performed using the working electrode,c. comparing the result of the first EIS and the second EIS,providing an indication indicating if the comparison results show a deviation between the first EIS and the second EIS exceed a predefined threshold.
