[Analysis Case] Evaluation of Coating Film on Injection Needle Surface

Visualization of the distribution and coating condition of water-repellent films, coatings, and membranes.

Medical injection needles reduce puncture resistance and lessen the physical burden on patients by coating the surface of the metal tube with silicone. To maintain the performance of the needle, it is important that the entire surface is covered with a coating film. This report introduces a case where imaging analysis of the opening at the tip of the injection needle was conducted using TOF-SIMS to evaluate whether the coating film was applied. Since TOF-SIMS detects information from the very surface, it can assess the condition of the coating film without detecting the underlying elements.
