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.*

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.

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at Idemitsu Plant Tech Chiba Co., Ltd. ~ In the case of Idemitsu Plant Tech Chiba ~ Before the introduction, there was a challenge to reduce the time spent on circulating and storing paper documents, as well as the approval process (including rejections). The decision to implement "Rakuraku Seisan" was made considering its proven track record in group companies and the cost benefits it offers. With the system in place, manual errors in data entry and accounting software have clearly decreased. The payment process for invoices used to take a total of 7 hours per month, but it can now be completed in just 4 hours. [Case Overview] ■ Challenges before implementation - Reduce the time spent on circulating and storing paper documents, as well as the approval process (including rejections). ■ Key points of implementation - Peace of mind due to proven track record in group companies. *For more details, please refer to the related links or feel free to contact us.

Caught up in daily input, approval, and checks, I want to improve but can't find the time to consider it. In back offices, which tend to fall into such a "negative loop," it's understood that system implementation can be a breakthrough, but the burden of the implementation itself is often significant, leading to new sources of concern. During the consideration phase, it takes time to request materials and compare demos, and even if the differences are clear, there is no certainty about whether it will fit the company. After implementation, issues often arise in operations, such as not being able to connect to support or having multiple inquiry points that cause confusion. Therefore, while organizing common failure cases, we have summarized key points for practical staff to proceed with a selection that is "smooth," "thorough," and "without regret." Common failure case 1: The purpose is vague, and "systematization" becomes the goal. Common failure case 2: It does not match the company's operations. Common failure case 3: Realizing it is "difficult" after starting to use it. Common failure case 4: Total costs balloon. You can read more without needing to input personal information.
