Eis fitting software5/29/2023 Without EIS Analyzer a dye manufacturer could only reproduce the resilience of his paint layer in practice. How resilient is a paint coating? In other words, how will a paint coat behave in time?.EIS Analyzer applications An EIS analyzer is mainly used for Electrochemical Impedance Spectroscopy (EIS) to investigate the electrical resistance (measured in Ohm) of substances and objects. If multiple frequencies are tested, single components and effects that are responsible for the resistance, can be identified. This allows the calculation of the electrical resistance of the liquid or object. The EIS Analyzer measures the difference between the maximum current and the minimum current (the height of the waves), but also the time difference between the potential wave and the current wave. This causes an electron current which also shows a wavy motion (Figure 1: green). EIS Analyzer measurements The potential wave (Figure 1: blue) provides periodical potential differences between electrode connected to the device and the object or the (liquid) substance in contact with the electrode. For example the can apply sinusoidal waves with a frequency between 1 MHz and 10 μHz. With an EIS Analyzer, this potential wave can be increased or decreased in a sinusoidal wave at an accurately controlled frequency. ![]() However a potentiostat is stable and the EIS Analyzer is continuously moving between a minimum and maximum. ![]() Just like a potentiostat an EIS Analyzer ensures that a potential is applied to a particular (liquid) substance.
