List of IDA electrodes w/o passivation membrane
There is a method for the calculation of the dielectric constant from the capacitance measured from the current intensity by the application of the alternative potential through the IDA electrode. However, for an IDA electrode with a passivation membrane, the capacitance of the membrane is also measured, making impossible to obtain the exact measured value. For this purpose, IDA electrode without passivation membrane was added to the product lineup.
