It is possible to measure the amount of residual oil adhering to metal parts.
Metal parts use various types of "oils" during the manufacturing process, but the oil that adheres to the surface can cause defects in subsequent processes such as painting and surface treatment. To avoid the occurrence of defects, it is important to manage the amount of oil adhered to the parts. The residual oil content can be quantified using FT-IR.

basic information
The oil adhering to the parts is collected, immersed in a solvent (carbon tetrachloride), and subjected to ultrasonic cleaning. The oil to be analyzed is diluted in the solvent to prepare several standard solutions. Using FT-IR, the FT-IR spectra of each standard solution are obtained. A calibration curve is used to convert the oil content of the solution recovered from the parts and quantify the residual oil content. If it is difficult to identify the adhering oil, quantification of the residual oil content can be achieved by using a standard substance (OCB mixed standard solution).
