ABSTRACT:
The invention pertains to a method and apparatus for the electrochemical analysis of solutions which comprises the measurement of an electric signal between a mercury column in a capillary and a reference electrode which are in contact with the analyzed solution sucked into the capillary. The mercury column in the capillary pulsates during the measurement. Current or voltage may be measured as the electric signal. An apparatus for the analysis of microliter volumes of solutions comprises a vessel for the analyzed solution provided with an inlet and outlet of the analyzed solution and a reference electrode, one end of a capillary is connected to the vessel for the analyzed solution and the other end of the capillary is connected to means for suction and ejection of mercury. A pulsator is attached to the capillary for moving the column of mercury and an electric contact is built into the capillary in contact with the mercury column. A measuring device is provided to measure the electric signal between the reference electrode and the electric contact.
