摘要： Provided is a method (100) for liquid impedance measurement using a four-electrode device comprising an electrode structure (210). The method (100) comprises applying (10) a sinusoidal voltage signal across a first outer electrode (202) and a second outer electrode (204) of said electrode structure and performing current and voltage measurements thereof. The method (100) further comprises applying (20) said sinusoidal voltage signal across a reference impedance (220) and performing current and voltage measurements thereof. The method (100) further comprises calculating an outer impedance between said first outer electrode (202) and said second outer electrode (204) based on a subset of the measurements. The method (100) further comprises calculating (40) an inner impedance between said first inner electrode (206) and said second inner electrode (208) a subset of the measurements, wherein the inner impedance represents the liquid impedance. A four-electrode device (200) for performing the method (100) is also provided.

摘要： A reference electrode (600) for being immersed in a bulk solution. The reference electrode comprises a reservoir (650) having reservoir walls defining a reservoir volume filled with an electrolyte; an electrode (620) in the reservoir, in contact with the electrolyte. The reservoir (650) of the reference electrode is closed except for the presence of at least one pore (651) in at least one of the reservoir walls, the at least one pore (651) being filled with electrolyte and being adapted for allowing ionic contact between the electrolyte in the reservoir and the bulk solution into which the reference electrode is to be immersed.
