[Analysis Case] Investigation of the Causes of Surface Stains and Water Repellency on Parts Using TOF-SIMS
Properly sampling and measuring surface contamination even on large parts that cannot be cut.
It was found that there are water-repellent stains on the surface of the aluminum material. The stained area was adhered to tape (transferred), and analysis was conducted using TOFSIMS. Fragments identical to those from the stained area on the aluminum surface were detected from the "tape surface where the stained area was transferred," suggesting that the substance causing the stain has been transferred to the tape. This method of transferring and collecting the causative substance onto tape is effective for parts that cannot be cut.
