DURCHFLUSSMESSZELLE MIT EINER VORRICHTUNG ZUR ÜBERPRÜFUNG DER POSITIONIERUNG UND DER BLASENFREIHEIT EINER MEDIZINISCHEN MIKROPROBE

摘要

Alternating- and measurement potentials are applied directly and simultaneously to individual electrodes (WE, RE, CE) in the electrode arrangement (2, 3). The alternating current component or the impedance is measured. The result is taken as an indication of micro probe (P) position and its freedom from bubbles (i.e. freedom from bubble-induced polarization) An Independent claim is included for the corresponding method.
