Total support service for chemical analysis
We conduct surface analysis, foreign substance analysis, and organic composition analysis.
At AITES, we propose and conduct contract analysis menus suitable for the purpose and sample, including the analysis of organic and inorganic substances, foreign substances, and surface analysis. In this department, we perform component analysis of microscopic foreign substances using advanced sampling techniques, as well as impurity analysis in samples, conducting both qualitative and quantitative analysis of organic and inorganic components. Additionally, we analyze the surface of samples for contamination and oxidation states. 【Service List】 ■ Component analysis of epoxy resin curing agents using Pyrolysis GC/MS ■ Analysis of microscopic organic foreign substances using Imaging FT-IR ■ Analysis of microscopic foreign substances using Micro-Raman spectroscopy ■ Ion Chromatography (IC) analysis, etc. *For more details, please refer to the PDF document or feel free to contact us.

Analysis of organic-inorganic composite materials using FT-IR and EDX.
We will introduce an example of analyzing organic-inorganic composite materials using FT-IR and SEM-EDX. FT-IR measurements were conducted on the glossy and non-glossy areas of a PET bottle label, and the IR spectra differed between the glossy and non-glossy areas. Since the non-glossy area resembles the spectrum of acrylic resin, it is considered that the main component is acrylic resin. Additionally, SEM-EDX measurements were performed on both the glossy and non-glossy areas, and EDX spectra and backscattered electron images were obtained, revealing that the non-glossy area contained sulfur (S) and barium (Ba), which were not detected in the glossy area.

Optical film light transmission characteristics
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.

Chemical Analysis Concierge Service
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.

Analysis of impurities in organic solvents
Here is an example of analyzing impurities confirmed from a solvent when high-purity products are stored in inappropriate environments. Ethanol stored in a light-protective reagent bottle in a cool, dark place was transferred to a used plastic wash bottle and left at room temperature for about a month. As a result, impurities such as triethyl borate and alkylbenzenes were detected. Additionally, acetone stored in a light-protective reagent bottle in a cool, dark place was transferred to a transparent glass bottle without light protection and left at room temperature for about a month, resulting in the detection of diacetone alcohol as an impurity. For more details, please refer to the related products and catalog below.

Analysis of LCD Display Materials
Liquid crystal displays use various organic materials, including liquid crystals, sealing materials, encapsulants, and polarizers. Considering the material properties and degradation mechanisms of each component from a chemical perspective is important for product evaluation and failure analysis. This document presents examples of chemical analyses for the components of liquid crystal displays. 【Examples of Chemical Analysis】 ■FT-IR: Principal component analysis ■EDX: Elemental analysis ■GCMS: Liquid crystal component analysis ■HS-GCMS: Outgassing analysis (degradation analysis) and others
