By adding a special reagent to the sample and heating it, it becomes possible to detect substances that are usually difficult to detect!

In a typical thermal decomposition GCMS, samples are heated to detect volatile components, but it is difficult to analyze components that do not volatilize upon heating or those with low detection sensitivity. Therefore, by adding a special reagent to the sample and heating it, it becomes possible to detect substances that are usually difficult to identify. For example, in the analysis of polymers, thermal decomposition of the polymer results in the detection of a large number of decomposition products, and in some cases, peaks may overlap with other additives, making analysis challenging. However, by performing reactive thermal decomposition GCMS, it is possible to detect the monomer methyl ester and to separate and analyze it from the additives. Thus, even when the target analyte is difficult to detect using conventional analysis, reactive thermal decomposition GCMS allows for sensitive detection by selecting appropriate reagents for the analyte.

Polyethylene (PE) comes in several types with different material properties depending on the length and number of its side chain branches. From the melting peak of crystalline polymer polyethylene, we measured the melting point and crystallinity using DSC and compared them by type of polyethylene.

In contrast, HDPE, which tends to have a denser molecular chain, showed high values for both melting point and crystallinity. Additionally, LLDPE, which has many relatively short side chains and is more likely to be dense than LDPE, exhibited intermediate values for both melting point and crystallinity between LDPE and HDPE. **Types of Polyethylene** - **LDPE (Low-Density Polyethylene):** Low rigidity and high flexibility - **LLDPE (Linear Low-Density Polyethylene):** Stronger than LDPE but inferior processability - **HDPE (High-Density Polyethylene):** High rigidity, excellent tensile strength, impact strength, and hardness *For more details, please refer to the PDF document or feel free to contact us.*

Important analysis items for performance evaluation and quality control of functional materials! Evaluation of pore size and pore distribution of non-woven sheets and membrane materials.

This is an example of evaluating the maximum pore diameter and pore size distribution of non-woven fabric sheets using the bubble point method. The sample is immersed in a chemical solution, and air pressure is applied. The pressure is increased until it overcomes the surface tension of the chemical solution absorbed in the sheet, at which point the appearance of bubbles occurs; this pressure is referred to as the bubble point. The maximum pore diameter can be calculated based on the bubble point pressure and the surface tension of the chemical solution. 【Calculation Formula】 ■d = Cy/P ・d: maximum pore diameter ・C: constant ・y: surface tension of the chemical solution ・P: differential pressure *For more details, please refer to the PDF document or feel free to contact us.

The Raman spectrum reflects the functional groups of organic compounds! The curing reaction can be estimated to some extent.

Our company analyzes the spectra of UV-curable resins before and after UV irradiation. We irradiate UV-curable resins (acrylic-based) with ultraviolet light and obtain Raman spectra before and after irradiation. Through the analysis of the Raman spectra, the curing reaction can be estimated to some extent. For a more detailed analysis of the curing mode, analyses such as GCMS are necessary, but our company can provide not only structural estimation but also reaction estimation through spectral analysis. 【Features of Raman Spectral Analysis】 ■ The curing reaction can be estimated to some extent. ■ We can accommodate not only structural estimation but also reaction estimation. *For more details, please refer to the PDF document or feel free to contact us.

We will be exhibiting at the only comprehensive and cross-sectional international convention in the marine field in Japan, "Techno-Ocean 2025." In this exhibition, we will introduce a wide range of specialized survey services related to offshore wind power generation projects, including wind and sea condition surveys, O&M, sediment surveys, and fishing ground environmental monitoring. We will also showcase marine surveys and seagrass bed investigations using marine robots such as autonomous surface vehicles (ASVs) and underwater drones, as well as the collection of dead fish in aquaculture operations.

The energy policy promoted by the government has finally made a significant shift from "quantity to quality." The previous large-scale introduction of renewable energy policies relied on inexpensive foreign-made panels, leading to the chaotic installation of mega-solar farms across Japan's land, which created environmental, landscape, and waste issues. As a result, Japan's energy self-sufficiency rate remains at a mere 13%, and even with the advancement of renewable energy, "import dependence" has not been resolved. In light of this reflection, the focus moving forward will be on "developing domestic energy technologies" and promoting "self-consumption type renewable energy." Among these, perovskite solar cells are lightweight, highly efficient, and offer great flexibility in installation, making them a trump card for "decentralized renewable energy" that can be easily retrofitted onto building walls and roofs. Kenneth Energy Development Co., Ltd. is developing a "selective self-consumption solar power generation system" that utilizes domestic panels and perovskite technology. Based on a track record of 83 projects nationwide and a total construction cost of 908.4 billion yen, it supports the industry's "energy independence." Now, renewable energy is entering an era of "security infrastructure."

"Perovskite solar cells" are once again emerging at the center of Japan's renewable energy policy. Mr. Takai has proposed "nurturing domestic technology for renewable energy" as part of energy and industrial policy, causing related stocks to attract attention in the market as the "Takai trade." The background to this is Japan's long-standing dependence on foreign-made panels in its renewable energy structure. While inexpensive imports have supported proliferation, they have also left a "negative legacy" of forest development, disposal risks, and price fluctuations. If this continues, both the land and energy supply will be controlled by foreign entities—this sense of crisis is the trigger for policy change. Perovskite solar cells possess the trifecta of being lightweight, highly efficient, and low-cost, making installation in existing buildings easy. Development is progressing as a domestic technology, and it is expected to become a mainstay for self-consumption power generation in the future. Kenneth Energy Development Co., Ltd. is developing a "next-generation self-consumption solar power system" with an eye on these perovskite cells. With over 8,000 installations nationwide and expertise in subsidy support, they are turning companies' "energy independence" into reality.
