Technical information "Evaluation of Coating Film on Injection Needle Surface (C0468)" and two other items published.

Inspection of various fiber products made from different materials is possible.

Nonylphenol ethoxylate (NPnEO) is used in industrial cleaning agents, but in January 2016, a restriction on the use of NPnEO in textile products was added to the European REACH regulation (Regulation on the Registration, Evaluation, Authorization, and Restriction of Chemicals). From February 3, 2021, the sale of specific textile products containing NPnEO (at 0.01 weight% or more) will be prohibited. This document presents the measurement results of NPnEO in various textile products.

We can conduct analysis of products, wastewater, and environmental water.

Organic fluorinated compounds are used in various applications such as surfactants and metal plating agents. Among them, perfluorooctanesulfonic acid (PFOS) is a substance regulated under the Stockholm Convention on Persistent Organic Pollutants (POPs), which restricts its manufacture, use, and import/export. Furthermore, the addition of perfluorooctanoic acid (PFOA) to the list of regulated substances is also being considered. In addition to PFOA and PFOS, perfluoroalkyl carboxylic acids (PFCA) and perfluoroalkyl sulfonic acids (PFAS) with different carbon chain lengths can also be analyzed simultaneously.

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.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
