Comparison of Infrared Spectroscopy and Raman Spectroscopy

By conducting two analyses, it is possible to obtain more detailed and accurate results!

This document introduces the characteristics of each spectroscopy method and the spectra obtained when comparing infrared spectroscopy and Raman spectroscopy. Both infrared spectroscopy and Raman spectroscopy are vibrational spectroscopies that investigate the vibrational energy of molecules, but the shapes of the spectra obtained from each method differ even when measuring the same substance. Infrared spectroscopy and Raman spectroscopy are complementary, and by conducting both analyses, information that cannot be obtained from either method alone can be acquired in a more detailed and accurate manner. For more details, please refer to the catalog provided. 【Characteristics of Infrared Spectroscopy】 ■ Infrared absorption occurs when the dipole moment changes with vibration (infrared active). ■ Vibrations that cause a distortion in electron distribution (breaking molecular symmetry) have high infrared activity. * For more information, please refer to the PDF document or feel free to contact us.

• Analysis and prediction system

Spectroscopic analysis is suitable for component analysis of foreign substances and qualitative analysis.

We will introduce a comparison between Raman spectroscopy analysis by Aites Co., Ltd. and FTIR. Spectroscopic analysis is suitable for component analysis of foreign substances and qualitative analysis. Both Raman and FT-IR can obtain spectra based on the structure of the analysis target. However, since each has its strengths and weaknesses, it is necessary to use both according to the analysis target. 【Features】 ■ Measurement in the order of a few micrometers, which is difficult with IR analysis, is possible. ■ No sampling is required. *For more details, please refer to the PDF document or feel free to contact us.

Detect and analyze the absorption wavelengths of organic molecular groups (functional groups)!

At Aites Co., Ltd., we conduct "FT-IR analysis" to confirm the degradation of resins. The degradation of resins can manifest as visible discoloration or invisible changes. Discoloration can be detected through changes in appearance, but invisible changes can lead to a decrease in strength and become the source of various issues. Analysis using IR allows us to understand the changes in molecular structure caused by these alterations. *For more details, please refer to the PDF document or feel free to contact us.*

We will suggest appropriate analysis methods based on the condition of polymer materials and samples!

At Aites Co., Ltd., we conduct material degradation analysis. We propose appropriate analytical methods based on the condition of polymer materials and samples. By analyzing the degradation process that the material has undergone and optimizing the polymer materials and usage environment, it is possible to extend the product's lifespan. *For more details, please refer to the PDF document or feel free to contact us.

It is possible to monitor the progress of the adhesive curing reaction (degree of curing)!

FT-IR spectra sensitively reflect the bonding state of organic materials, making it possible to monitor the progress of adhesive curing reactions (degree of curing). The procedure for measuring the degree of curing of the resin involves comparing the spectra of unreacted materials with those of materials after 100% reaction to identify the changing regions. The degree of curing for unreacted materials is set at 0%, and that for reacted materials is set at 100%. The peak intensity of the measurement sample spectrum is interpolated to determine the reaction rate (degree of curing). 【Procedure for Measuring Degree of Curing】 ■ Compare the spectra of unreacted materials with those of materials after 100% reaction to identify the changing regions. ■ Set the degree of curing for unreacted materials at 0% and for reacted materials at 100%. ■ Interpolate the peak intensity of the measurement sample spectrum to determine the reaction rate (degree of curing). *For more details, please refer to the PDF document or feel free to contact us.

Analysis of inorganic compounds such as metal oxides is also possible! We will introduce the analysis of black spots on the surface of copper-clad laminates.

We would like to introduce a case where discoloration on the surface of a copper-clad laminate was analyzed using Raman spectroscopy. Our Raman spectroscopic analysis can analyze not only organic substances but also inorganic compounds such as metal oxides. Please feel free to contact us when needed. [Analysis Details] ■ Analysis of black spots on the surface of the copper-clad laminate - Slight discoloration is observed on the surface - Upon magnification, a condition resembling black stains is seen - A spectrum of CuO was obtained from the discolored area - The nature of the discoloration is believed to be copper oxide formed on the surface of the copper *For more details, please refer to the PDF document or feel free to contact us.

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.

From June 2025, measures against heat stroke in the workplace have become mandatory. Additionally, in December 2026, a "Support Package for Heat Wave Measures in Construction Work" was formulated, making heat stroke prevention during the summer a pressing issue, especially for those engaged in the construction industry. This time, we provide a collection of heat stroke prevention materials that can be utilized through Sysmet Co., Ltd.'s comprehensive weather platform, ZEROSAI X-AI. Examples of heat stroke prevention measures possible with ZEROSAI X-AI: - Cloud management of heat stroke information - Forecasting of the heat index (WBGT) tailored to the site with a mesh of 500m for up to 17 days ahead - Observation of the heat index (WBGT) in compliance with JIS standards using a black globe thermometer - Alerts for exceeding work standard values for the heat index (WBGT) via electronic bulletin boards, emails, and business chat tools like direct LINE WORKS We hope this will be useful at your sites as well.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

In facilities operating nurse call systems, we have made bed exit sensors wireless, allowing them to notify in conjunction with the nurse call system.
