Depth-direction measurements using Raman spectroscopy! Material analysis of each layer is possible from the surface of multilayer films.

Our "Micro Raman Spectrophotometer" employs a confocal optical system, allowing for the adjustment of the focal position in the depth direction, similar to a microscope, enabling material analysis of each layer from the surface of multilayer films. Using the confocal function of the micro Raman spectrophotometer, the focus of the Raman laser light can be varied in the depth direction. Additionally, by continuously changing the focal position, it is possible to obtain spectra continuously in the depth direction. 【Features】 ■ Adoption of a confocal optical system ■ Enables material analysis of each layer from the surface of multilayer films ■ Capable of varying the focus of the Raman laser light in the depth direction ■ Allows for continuous spectral acquisition in the depth direction *For more details, please refer to the PDF document or feel free to contact us.

Distinguish compounds with similar molecular structures through NMR analysis, elucidating the binding positions of side chains and substituents, as well as branching structures!

At Aites Co., Ltd., we conduct 1H NMR analysis of phthalate esters. NMR analysis is an effective method for distinguishing compounds with similar molecular structures and elucidating structures such as the bonding positions of side chains and substituents, as well as branching structures. In organic synthesis and polymer synthesis, it is an essential analysis to confirm whether the desired molecular structure has been obtained. The characteristic effects and efficacy of pharmaceuticals, supplements, food, and fibers are influenced by the positions of substituents in the molecular group and the molecular structure. Our skilled team will provide in-depth organic molecular structure analysis. *For more details, please refer to the PDF document or feel free to contact us.

Analyze trace components in materials using thermal desorption GCMS! We perform characterization of various materials.

Aites analyzed photopolymerization initiators in UV-curable resins using GCMS and detected Irgacure 184, a type of photoinitiator (photo radical polymerization initiator). There are various structures of photoinitiators, and the wavelength of light they absorb and their reaction mechanisms differ depending on their structure. Such substances cannot be identified through main component analysis like IR, making thermal desorption GCMS analysis effective. Our company conducts characterization of various materials by analyzing and identifying trace components in materials using thermal desorption GCMS. Please feel free to contact us when needed. [Examples of photoinitiators] ■ Photo radical polymerization initiators ■ Photoinitiators for positive photoresists ■ Light crosslinking agents for negative photoresists *For more details, please refer to the PDF document or feel free to contact us.

Essential materials alongside metals and inorganic materials! Introducing examples of analysis and evaluation services for organic materials.

Organic materials such as solvents, additives, pharmaceuticals, and plastics are essential materials alongside metals and inorganic materials. They have a wide variety of types due to combinations of light elements, and their specificity arises from structures, intermolecular forces, and electron behavior. However, it seems that chemical instrumentation analysis and evaluation are necessary for a fundamental understanding of their properties. This document presents examples of analysis and evaluation services for organic materials.

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 resin (acrylic type) 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 provide support for both structural estimation and reaction estimation. *For more details, please refer to the PDF materials or feel free to contact us.

The "Mechanical Stitching 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 on 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.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

Are you struggling to explain "safety" to the client using just drawings? - The risks in blind spots are difficult to convey to the client through drawings alone. - Safety measures often become a target for cost reduction, making it hard to communicate their necessity. - There is a concern that the client might say, "It's more dangerous than I thought," after completion. Risks that are visible to design professionals are not easily understood intuitively by clients who are outside the field. This document is not just a simple explanation of sensor functions; it is a guide to visually explain "why sensors are necessary in that location." It can be used directly as explanatory material for the client. Here are three key points for utilizing this document: 1. Visualization of Risks Blind spots during vehicle departure and contact risks within the site are illustrated clearly. 2. Clarification of Selection Criteria A comparison table outlines the differences between complex sensor types such as infrared, ultrasonic, and loop coils. 3. Diagram of System Configuration It illustrates not just the sensors alone, but how they combine with components like rotating lights and control panels, providing practical assistance for electrical equipment design. Please make use of this to prevent "rework after completion" and "accident risks."

In facilities operating nurse call systems, we have made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call system. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. This helps prevent accidents caused by falls, slips, or wandering, contributing to the efficiency of medical operations. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call system. ○ Up to 5 transmitters can be registered with a single receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.
