Measurement of Oil Residues on Metal Pipes Using the TOC Solid Sample Measurement System

Introduction

Various metalworking fluids are used in the process of working metal materials. The fluids used vary according to the type of metal and functionality that is in need. Their main components include oils, surfactants, and pH control agents to achieve functions such as lubricity, durability, and cleanability. Depending on the residual amount of such fluids, the quality of the product in which the metal parts are incorporated may be adversely affected, which is why the evaluation of the residual content of metalworking fluids is considered important in quality control. The TOC-L Total Organic Carbon Analyzer and SSM- 5000A Solid Sample Combustion Unit comprise a system which can measure the amount of organic substances contained in a solid sample. In this research, we prepared stainless steel pipes as metal material samples, and used this system to measure the oil residues on the surface of the stainless steel pipes.
