[Data] FT-IR Analysis of Transparent Resin

At Aites Co., Ltd., we conduct "optical film analysis." Optical films used in smartphones and other devices have various functions depending on their structure and materials. We measured the light transmittance of privacy protection films at different angles and combined cross-sectional observation with Raman analysis to investigate the mechanism of function manifestation. By investigating the transmittance characteristics of privacy protection films using angle-variable spectrophotometry, we were able to analyze the mechanism of function manifestation through cross-sectional observation and Raman analysis. At Aites, we provide consistent evaluation and analysis from material properties to the mechanisms of function manifestation.

At Aites Co., Ltd., we have newly introduced "Microscopic FT-IR" this fiscal year. The "Microscopic FT-IR," which combines FT-IR and optical microscopy, allows for the measurement of tiny substances on the order of several tens of micrometers, which are difficult to measure with conventional FT-IR, using an aperture (field of view diaphragm). There are three main measurement methods for Microscopic FT-IR: "transmission method," "reflection method," and "ATR method." While the transmission method is the basic measurement method in Microscopic FT-IR measurements, the reflection method or ATR method may be more suitable depending on the shape of the sample and the feasibility of sampling.

We would like to introduce our "Chemical Analysis - Trust Us Service." When conducting component analysis of foreign substances or stains on products, it can be challenging to determine whether organic analysis or inorganic analysis is more suitable, and which specific analysis within organic or inorganic is the most appropriate. We provide a comprehensive service for customers who are struggling with the selection of analysis methods. Since each analysis device can measure different targets, it is necessary to choose a method that fits the purpose based on the information available.

Our company analyzes the spectra of UV-curable resins before and after UV irradiation. We irradiate UV-curable resin (acrylic type) with ultraviolet light and obtain Raman spectra before and after irradiation. By analyzing the Raman spectra, we can estimate the curing reaction 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.
