Evaluation of Oil Residues on Aluminum Foil Surfaces

User Benefits

- The quality of metal foils, such as aluminum foil, can be managed swiftly and effortlessly. - Organic contaminants, including oils that don’t dissolve in extraction solutions with traditional methods, can also be measured. - Given each measurement takes about 5 minutes, the quick and easy analysis is also suitable for handling large number of samples.

Introduction

Aluminum foil is integral to a variety of applications, especially in determining the quality of certain electronic components like aluminum electrolytic capacitors. One of the critical factors influencing foil quality is residues of oil applied as a lubricant on its surface during the rolling process. To ensure optimal product performance, it is essential to manage the oil levels on the surface of aluminum foil. The Shimadzu TOC-L total organic carbon analyzer combined with an SSM-5000A solid sample combustion unit serves as a system for measuring carbon content in solid samples. Unlike traditional methods, which often require laborious extraction with reagents, this method can identify organic impurities, such as non-soluble oils in the extraction solutions. That results in a swift and straightforward approach to quality control of aluminum foil. This article describes an example of measuring the oil on the surface of aluminum foil using the Shimadzu TOC solid sample measurement system.
