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.

[To the owners of parking lots and parking lot construction companies] "I'm worried about not colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, particularly at entrances facing sidewalks or roadways, there is a risk of dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures using various sensors and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "sensor" + "controller" + "switching power supply (24V)" + "LED rotating light." *Please note that a separate control panel is required to include the controller and switching power supply (24V) when using the exit warning system. *We kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breakers, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. We hope this will contribute to safer vehicle passage for everyone. ◎ For more details, please contact us or download the catalog.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.
