Aluminum electrolytic capacitor lengths are cut off, as required, for capacitor production. The electrolytic capacitor got its name from the electrolyte, the conductive liquid inside the capacitor. As a liquid it can be adapted to the porous structure of the anode and the grown oxide layer with the same shape and form as a "tailor-made" cathode. An electrolyte always consists of a mixture of solvents and additives to meet given requirements. The main electrical property of the electrolyte is its conductivity, which is physically an ion-conductivity in liquids. In addition to the good conductivity of operating electrolytes, various other requirements are, among other
Polarograph Polarograph A Polarograph is a chemical analysis instrument used to record automatic voltage-intensity curves. The Polarograph uses an electrolytic cell consisting of an electrode or microelectrode small area, generally of mercury drop type , which is a very fine capillary tube through which mercury flows slowly , which comes in the form of small droplets, which fall on the same surface of a much broader element, which is the other electrode . When one applies a variable voltage in this cell, the electrode large area remains unchanged, while the microelectrode undergoes a change of potential ,( i.e. is polarized). It
