We will introduce a case where ICP measurement was conducted using panels before and after reliability testing, and quantification was performed. The liquid crystal molecules in an LCD are oriented within the panel, and the display is controlled by changes in the orientation state of the liquid crystal due to voltage. When ionic substances, such as metal elements, are present inside the panel, the liquid crystal does not operate correctly, leading to display defects. It is known that ionic substances can increase due to contamination during manufacturing or long-term use, making it important to quantify and understand them as part of panel quality. Metal ions can be quantitatively analyzed using ICP analysis, and depending on the differences in pretreatment methods and detection sensitivity, ICP-AES/MS is used selectively.

We conducted hardness measurements on aluminum spot welds after performing cross-sectional observations, and we would like to present an example of the trends observed in Vickers hardness, Young's modulus, and elasticity ratio. From X-ray radiographic observations, voids were confirmed within the weld area. Cross-sectional observations revealed that the void in the center was a blowhole. Additionally, the hardness measurement results indicated that the area near the blowhole was hard but had low stiffness, making it prone to deformation, while areas slightly away from the blowhole exhibited higher stiffness and were somewhat brittle.

Dynamic light scattering allows for the measurement of particle size and size distribution of nanoparticles dispersed in a liquid without separating the particles. Here, we present examples of particle size measurement for silica and alumina particles in an aqueous medium. Particles in solution exhibit Brownian motion that depends on their size, and the fluctuations in the scattered light generated when the particles are illuminated depend on the particle size. By observing and analyzing these fluctuations, we can determine the particle size and size distribution. [Alumina Measurement Results and Discussion] - As alumina approaches neutrality from strong alkaline conditions, it approaches its isoelectric point. - The surface charge of the particles decreases. - The repulsion between particles diminishes. - It can be inferred that particle aggregation is occurring. *For more details, please refer to the PDF document or feel free to contact us.*

Polyethylene (PE) comes in several types with different material properties depending on the length and number of its side chain branches. From the melting peak of crystalline polymer polyethylene, we measured the melting point and crystallinity using DSC and compared them by type of polyethylene. LDPE, which has many long side chains and is less dense, resulted in a low melting point and low crystallinity. In contrast, HDPE, which tends to have a denser molecular chain, showed high values for both melting point and crystallinity. Additionally, LLDPE, which has many relatively short side chains and is more likely to be dense than LDPE, exhibited intermediate values for both melting point and crystallinity between LDPE and HDPE. **Types of Polyethylene** - **LDPE (Low-Density Polyethylene):** Low rigidity and high flexibility - **LLDPE (Linear Low-Density Polyethylene):** Stronger than LDPE but inferior processability - **HDPE (High-Density Polyethylene):** High rigidity, excellent tensile strength, impact strength, and hardness *For more details, please refer to the PDF document or feel free to contact us.*

"Energy Dispersive X-ray Spectroscopy (EDS or EDX)" is a method for obtaining elemental information about samples or foreign substances by detecting characteristic X-rays generated by electron beam irradiation using a detector attached to an electron microscope (SEM or TEM). When characteristic X-rays generated by irradiating a material with an electron beam enter the detector, a number of electron-hole pairs equivalent to the energy of the characteristic X-rays are produced. By measuring this number (current), it is possible to determine the energy of the characteristic X-rays, and since the energy varies by element, it is possible to investigate the elemental information of the material. 【Analysis by EDS (Partial)】 ■ Qualitative analysis of intermetallic compounds (point analysis) - By examining which element's characteristic X-ray energy corresponds to the characteristic X-rays in the measured spectrum, it is possible to determine the type of elements. ■ Semi-quantitative analysis of intermetallic compounds - By examining the intensity (count number) of each characteristic X-ray, it is possible to calculate the concentration of the contained elements. *For more details, please refer to the PDF document or feel free to contact us.
