In this webinar, we will explain "Why packed columns continue to be chosen today" from a practical perspective of gas analysis. We will also introduce the various types and characteristics of packing materials offered by Restek, along with application examples, and share insights on how to make optimal choices based on analytical objectives. Furthermore, we will discuss the differences in hardware passivation techniques and how to differentiate their use, as well as examples of custom packed column designs tailored to specific purposes. Topics covered in the webinar: ✅ Types of packing materials for packed columns and their characteristics ✅ Differences in separation selectivity based on analytical examples for each packing material ✅ Examples of custom packed column designs Benefits: For beginners: You will gain an understanding of separation selectivity based on differences in packing materials and the basics of column selection. For intermediate and advanced users: You will gain a concrete understanding of how to select packing materials and the usefulness of custom packed columns to improve separations that do not satisfy with existing columns. Participant benefits: We will provide a collection of packed column applications that are not publicly available.

Nitto Kohki will exhibit at the "30th Mechanical Components Technology Exhibition [Tokyo]" held at Makuhari Messe Hall 5 from July 9 (Wednesday) to July 11 (Friday). [Booth Number: Hall 5 31-32] At this exhibition, we will showcase a variety of products, including the electric suction hand "e-VEE" with a built-in pump that does not require compressed air, a cordless belt sander, the electric driver "Delvo" that can be mounted on robots, and the "Flow Monitor" that allows for easy visualization of the flow of cooling water in molds and other applications.

In "The Principles of Mixing and Defoaming and Key Points for Recipe Setting," we will explain the mechanism of the self-rotating and orbiting mixer, Awatori Nentaro, and the principles of mixing and defoaming in an easy-to-understand manner for beginners. ◇ Why do materials mix just by combining centrifugal force? ◇ What does it mean that mixing and defoaming can be processed simultaneously? ◇ How do the materials inside the container move during operation? This content is recommended for those who usually use Awatori Nentaro in their work but have never heard about its mechanism or principles and want to learn about it on this occasion. We will also explain temperature management based on material viscosity and considerations for operating conditions with examples. Additionally, in the "Legal Self-Inspection and Basic Maintenance Training," participants will have the opportunity to experience basic maintenance such as round belt replacement and legal self-inspection (regular self-inspection) using actual equipment. The capacity for each seminar is different, so please apply early! ◆ Date and Time: April 24, 2026 (Friday) 13:00 - 16:30 ◆ Venue: Hiroshima Convention Hall
