Evaluation of cleanliness of aluminum foil surface using the Shimadzu Total Carbon Analyzer

Introduction

Nowadays, with the spread of mobile phones and other mobile communications, there is an increasing demand for high purity aluminum electrolytic capacitors. The material for the electrodes in aluminum electrolytic capacitors is aluminum foil, and it is one important part that affects quality. When the aluminum foil is rolled during processing it is coated with lubricating oil, but if residues of this oil remain on the aluminum foil the characteristics of the final product are deteriorated. Therefore, in order to manufacture high-quality products, there is a demand for high sensitivity control of oil residues on aluminum foil surfaces.
