Our organization offers three-dimensional structural analysis of 3D printed objects. Understanding the differences between the design drawings and the manufactured products is an important process in quality control. By conducting X-ray CT measurements, it becomes possible to compare the three-dimensional structural "discrepancies" between the printed objects and the design drawings, allowing for an evaluation of the quality. In this case study, we are evaluating molded products made from resin-based materials, but similar evaluations can also be conducted for molded products made from metal-based materials that allow X-rays to pass through.

Our organization offers dynamic viscoelastic evaluation of PDMS using AFM. Dynamic Mechanical Analysis (DMA) is an effective method for investigating viscoelastic behavior, which is an important factor in the research and development of polymer materials. Additionally, by combining it with the AFM mechanism, it becomes possible to measure in-plane distribution and evaluate localized areas. This document presents a case study using AFM-DMA to map the viscoelastic modulus of PDMS (polydimethylsiloxane) and conduct frequency-dependent spectroscopy evaluation.

Our organization offers composition distribution evaluation of organic films using Raman mapping. The properties such as mechanical characteristics, thermal resistance, and durability change by mixing materials. It is important to link material properties with mixing conditions in material development, and using dispersion as an indicator is effective. This document presents a case study of mapping the distribution of PS (polystyrene) and PCL (polycaprolactone) using Raman. By comparing the characteristic Raman peaks of each material, it is possible to separate the components of the mixture. Component separation from PCL was performed through spectral analysis around the PS-specific peak at approximately 3050 cm-1.

Our organization offers evaluation of the crystallinity of carbon materials using Raman mapping. Carbon materials possess different properties depending on their structure and crystallinity, and are used in various applications such as industrial components and medical devices. Linking the characteristics of materials to their crystallinity is effective as an indicator for material development. This document presents a case study where the in-plane distribution (peak intensity) of diamond particles, a carbon material applied to the surface of components, and the crystallinity (full width at half maximum) of each diamond particle were evaluated using Raman mapping. Diamonds exhibit a sharp peak observed sensitively at 1330 cm-1, making Raman evaluation effective.

Our organization is capable of identifying the composition of petroleum products, evaluating molecular weight distribution, and distinguishing types of oils. Petroleum products such as oils and greases are mixtures of hydrocarbons with various compositions, and GC/MS methods are effective for their qualitative analysis. Here, we present a case study where commercially available oils with different molecular weight distributions were measured using soft ionization methods. Compared to hard ionization methods (EI), soft ionization methods (FI and FD) allow for the detection of molecular ions, making them effective for evaluating the composition of oil components. In particular, the FD method can also be applied to evaluate oils containing high molecular weight components that are difficult to volatilize.

Our organization offers analysis of the end group structure of polycarbonate. Polycarbonate is an engineering plastic known for its excellent impact resistance and heat resistance, and it is widely used as a material in electrical, electronic, and optical devices. There are mainly two methods of manufacturing polycarbonate, and the end group structure, which affects the physical properties of the polymer, varies depending on the manufacturing method. Since the end group portion of the polymer is small compared to the main chain, the analytical methods available for its structural analysis are limited. Here, we present a case study evaluating the end group structure of polycarbonate using thermal decomposition GC/MS.

Our organization conducts observations of structural changes in ABS resin through tensile testing using in situ X-ray CT. In in situ X-ray CT measurements, it is possible to perform structural observations while applying a load (tensile or compressive) to the sample. In this case, X-ray CT measurements were conducted on a sample of ABS resin containing glass filler under tensile load, and the tensile stress applied to the sample was calculated. The three-dimensional structural changes of the resin and glass filler under each stress condition were monitored.

Our organization conducts metal analysis in organic materials. Metal components can cause a decrease in insulation properties when they contaminate organic materials, such as in semiconductor devices. Therefore, it is important to understand the amount of metal in organic materials. In this case, we analyzed the metal content in organic materials (polyethylene products, polypropylene products, polyimide films). Organic materials can be acid-digested by irradiating them with microwaves in a sealed state (under high temperature and pressure).
