Analysis of fragrance components by GC-MS

GC-MS is used for qualitative and quantitative analysis of low molecular weight organic substances! Data was obtained and compared using incense and sandalwood!

Using fragrance as a keyword, we analyzed familiar incense and compared the characteristics of its molecular structure with other materials. The three representative aromatic woods obtained from trees are sandalwood, agarwood, and kyara; in this case, data was collected from incense and sandalwood. It is speculated that the woody scent is primarily due to the aliphatic cyclic structure, characterized by aldehyde groups. [Analysis Overview] ■ Analysis Samples: Incense, Sandalwood ■ Identification of fragrance components using thermal desorption GC-MS (180°C) - Confirmed peaks with the same detection time as sandalwood - Indicates that sandalwood is used as a fragrance in the incense *For more details, please refer to the PDF document or feel free to contact us.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

Seven Corporation has begun research and development related to rust prevention, aiming to expand the functionality of the natural multifunctional aqueous solution "SEA'S 7." This research is being promoted as a collaborative study with the Industrial Technology Research Institute. In recent years, the manufacturing industry has been seeking technologies that balance environmental impact reduction and improved work safety, making rust prevention measures after cleaning a critical issue. This research includes corrosion evaluation using metal test pieces, measurement of weight changes, and durability tests in a circulating water environment, advancing the understanding of rust prevention mechanisms and performance evaluation. In the future, we aim to develop a next-generation SEA'S 7 that incorporates rust prevention functionality in addition to cleaning, disinfection, and deodorization, contributing to the efficiency of manufacturing processes and the reduction of environmental impact.

We are pleased to announce the launch of the "Vertical Aluminum Step Type F." The "Vertical Aluminum Step Type F" is a new type of aluminum ladder specifically designed for excavation sites, based on the existing "Vertical Aluminum Step." The vertical aluminum step is lightweight due to its aluminum construction, making it easy to transport and set up. Additionally, its modular design allows for flexible height combinations (with connecting parts of 0.7m, 1.0m, and 2.0m). The newly launched Type F retains the features of the previous model while providing even greater convenience. <Features of Type F> ■ The hook adjustment range of the fixed part has been expanded.

The stand pipe can be stored, making transportation and storage easier. <Release Date> January 5, 2026 <Specifications> - Standard set for Type F: 2.4m *Individual sales of the hanging fixed part and connecting parts are available. *Sales of the previous model (stand pipe fixed type) will also continue.

This time, we will explain the differences in roles between the "accounting system" and the "document management system," which are surprisingly not well known, as well as points that are often overlooked in legal compliance. ■ The difference between accounting systems and document management systems is their "scope of coverage." - Accounting System = Management of "money (numbers)" - Document Management System = Management of "evidence (documents)" ■ Documents that are often overlooked in accounting systems The accounting system primarily focuses on "accounting processes." - "Estimates" where no money movement occurs - "Delivery notes" and "purchase orders," which are intermediate points in transactions ⇒ There are cases where these are not saved or managed in the accounting system. This could be considered a deficiency under the Electronic Bookkeeping Act. ■ Supplementing the missing parts with an "independent system" While there are high-function ERP (Enterprise Resource Planning) systems that can manage everything from estimates to invoicing seamlessly, the reality is that the cost can be a significant barrier to implementation. Therefore, there is also the option of managing documents with an independent document management system like paperlogic. Paperlogic is currently offering a free trial. Please feel free to contact us.
