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 acquire 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 acquisition of spectra 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 bonding 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 targeted 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.

Analysis of 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 (light 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] ■ Light 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 the combination of light elements, and their specificity is manifested through structure, 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 case studies 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 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.

In preparation for this summer's extreme heat, we have completed a "Heatwave Countermeasure Catalog" that will help improve the working environment in the manufacturing and logistics industries. The catalog includes a wide range of products for facility improvements, such as fireproof certified heat-shielding sheets that cut radiant heat by 97%, heat-shielding curtains, roof and window countermeasure products, and fans suitable for large spaces, as well as black globe thermometers that can measure WBGT, wearable alert bands, mobile cooling shelters, and fan-equipped work clothing. We have consolidated measures for "building countermeasures," "work space countermeasures," and "personal countermeasures" into one volume. It can also be used as reference material for discussions in safety and health committees. Please take a look at the specific measures that simultaneously achieve heat countermeasures and energy conservation/CO₂ reduction.

We have recently started a demonstration experiment aimed at addressing antibiotic-resistant bacteria in dairy farming. Utilizing compost environments, we will examine the impact of using our technology-based aqueous solutions on microbial dynamics. This experiment is being conducted with field cooperation, aiming to establish a new approach that contributes to the realization of a sustainable livestock environment and the reduction of antibiotic usage. In this trial, we will set up a spray group (Group H) and a non-spray group (Group C), and will conduct a time-series comparison before spraying, immediately after spraying, and at 1, 3, 7, 14, 28, and 42 days, as well as at the maturation stage. We will perform sampling from the upper, middle, and lower layers of the compost at a depth of 10 cm, while simultaneously collecting temperature logs (external temperature and two internal compost temperatures) to analyze microbial changes and fermentation status from multiple angles. Based on scientific data, we will pursue a balance between safety and effectiveness, and work towards contributing to the livestock industry.
