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.

• Measurement and Analysis Equipment

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.

When thinking about the first impression of a store or office, one might envision the entrance, reception, and interior design, but in fact, the "restroom space" is also an important element. No matter how clean a store is, a poor impression of the restroom can lead to a negative overall image. On the other hand, by creating an environment with: - A clean and pleasant scent - A luxurious atmosphere - An odor-free environment customer satisfaction can be improved. Recently, many facilities such as restaurants, beauty salons, offices, and clinics have introduced scent experiences in their restrooms. Majesta Fragrance offers scent solutions tailored to various spaces, including stores, salons, offices, clinics, and sports clubs. We have many options for restroom spaces, and our compact model "MFmini" is available starting at 4,400 yen (tax included) per month. Because it is a small space, the effects of scent can be felt more significantly. "For those who want to try out the scent in person," we also offer free trial installations. Why not start creating a space that customers choose with the power of scent? If you are interested in scent experiences, please feel free to contact us.

If you are considering "scent marketing (aroma branding)" for your store or office in Chiba Prefecture, please leave it to Majesta Fragrance! Our company helps enhance the added value of spaces through our rental service for commercial aroma diffusers. A free trial installation is also available. If you are interested in scent marketing, please feel free to contact us.
