We will exhibit at the 2025 Cleaning Comprehensive Exhibition.

Would you like to save energy by conserving water through tank cleaning?

**Features** Rehira Corporation has established five classes based on cleaning power. Rotary cleaning nozzles of class 2 and above commonly adopt a "low-pressure specification" that saves energy and is less prone to wear, as well as a "cleaning head" that is lubricated with cleaning fluid. The series that employs a "free-spinning head" lifts dirt with strong repetitive impacts and washes away tank contaminants, while the series that uses "internal drive control" maintains head speed to provide powerful spray effects by harnessing liquid flow to power the internal turbine head, making it suitable for large tank cleaning. We also offer sprays for cleaning relatively small tanks centered around class 1, which includes fixed cleaning nozzles, and we have various tank cleaning nozzles available, allowing us to recommend cleaning nozzles tailored to the size, shape, and purpose of your tank. **Differences from Other Companies** Our company can conduct tests on a PC using software for "visualization" before performing actual machine tests. Please feel free to contact us for inquiries.

The particle visualization technology developed under our brand "ViEST" has a very high level of detection sensitivity, capable of visualizing the suspended or adhered states of micro and nano-sized particles in real time. We are engaged in the sale of visualization systems and contract services for evaluation (investigating particles and airflow in production processes, inside and outside manufacturing equipment, evaluating the performance of cleaning products, proposing yield improvement measures, etc.) both domestically and internationally. In manufacturing environments, invisible fine foreign substances, dust generation, particle adhesion due to static electricity, and airflow disturbances can cause quality defects and reduced yield. Our company clarifies these contamination factors through visualization technology and provides consistent support from identifying the source of the problem to considering and confirming improvement measures. Do you have any of the following concerns? - Unable to identify the cause of foreign matter contamination - Want to check airflow and cleanliness in clean rooms - Want to understand dust generation from manufacturing equipment and transport systems - Want to reduce particle adhesion to films and substrates - Want to improve contamination that leads to reduced yield

In this seminar, we will focus on the challenges of sensitivity reduction and separation performance in GC/MS analysis, and introduce the latest technologies and practical know-how that can help solve these issues. This time, we will also have a presentation from LECO Japan, who will discuss the benefits and applications of high-resolution and high-separation analysis with real examples. Additionally, Restek will introduce column technologies effective for improving sensitivity in trace analysis. Restek: We will explain the inert performance of the RMX GC column, which is effective for improving sensitivity in trace analysis, and the column technology that suppresses adsorption loss in low concentration areas, along with actual measurement data. LECO: We will present the latest application examples of comprehensive detection of trace components using high-sensitivity GC-TOFMS and RMX columns, including environmental, aroma, and material analysis. This content is recommended for anyone involved in multi-component analysis using GC/MS, whether for target or non-target analysis, as well as those who are just starting out. We will provide clear explanations suitable for beginners in GC/MS, so please join us.
