Reliability testing of materials and chemical analysis evaluation after testing.

Reliability testing of materials and chemical analysis evaluation after testing.

Introducing a case where the changes in molecular structure of materials were verified through IR analysis! We also creatively accommodated a variety of sample setups.

Reliability testing of materials that make up the product under thermal and humidity loads is essential, but analysis and evaluation after testing is also an indispensable process. Constant temperature and humidity testing is a device that applies temperature and humidity loads to products and materials to check for changes in physical properties, characteristics, appearance, and lifespan. Our company has also devised various methods for setting up a wide range of samples. In this document, we will introduce a case where changes in the molecular structure of materials before and after constant temperature and humidity testing were verified through IR analysis. We encourage you to read it. [Contents] ■ Examples of reliability testing equipment (constant temperature and humidity testing equipment) ■ Innovations in sample setup ■ Comparative evaluation before and after testing through chemical analysis *For more details, please refer to the PDF document or feel free to contact us.

Evaluation of distortion and birefringence of products/materials by WPA.

Evaluation of distortion and birefringence of products/materials by WPA.

By evaluating the orientation, strain, and birefringence of the material, you can understand the internal stress and strain state!

The materials that make up the product are varied, but if there is significant or uneven internal stress during the manufacturing process, it can lead to issues such as deformation, cracking, and reduced performance due to usage and environmental conditions. By using 'WPA (Wide Polarization Analysis)', it becomes possible to understand internal stress and strain states by evaluating the orientation, strain, and birefringence of the material. Please feel free to consult with us. 【Features】 ■ Ability to understand internal stress and strain states ■ Clarification of material strain and birefringence from a molecular perspective ■ Analysis of defects and theories through multiple methods in a matrix - Raman spectroscopy (qualitative/strain/crystallinity), XRD (X-ray diffraction), AFM/SEM/TEM (crystal structure observation), DSC (degree of crystallization), etc. *For more details, please refer to the PDF document or feel free to contact us.

Evaluation of particle size of positive electrode active material

Evaluation of particle size of positive electrode active material

Introducing examples of measurement cases for important management items in the production of lithium-ion batteries and all-solid-state batteries!

We would like to introduce a case of particle size measurement of cathode active materials using laser diffraction conducted by our company. In air or liquid, laser light is irradiated onto particles, and the angular dependence of the intensity of light scattered by the particles is measured. The angular dependence of the scattered light intensity is measured, and from that data, the particle size distribution (particle size distribution) is calculated. Commercially available reagents were used as samples, and measurements were conducted in a dry state without dispersing in a solvent. The particle size measurement results for NMC oxide showed a monodisperse state with particle sizes below several tens of micrometers, and the median diameter was calculated to be 12 μm. 【Case Overview】 ■ Measurement Method ・Dry ■ Particle Size Measurement Results for NMC Oxide ・Monodisperse state with particle sizes below several tens of micrometers ・Median diameter is 12 μm *For more details, please refer to the PDF document or feel free to contact us.

Distortion evaluation using SEM equipment

Distortion evaluation using SEM equipment

EBSD: Electron Backscatter Diffraction

Measurements can be performed in bulk state without the need for thinning processes like TEM (NBD: Nano Beam Diffraction). It has the high spatial resolution characteristic of SEM and relatively high strain sensitivity. Additionally, there is a possibility of detecting local lattice strain as tensor data.

Cryo-SEM analysis: Evaluation of the dispersion state of microparticles in liquid.

Cryo-SEM analysis: Evaluation of the dispersion state of microparticles in liquid.

By rapid freezing and SEM observation, the dispersion of particles was confirmed through images! ★Data displayed at the 25th Interphex Japan★

When evaluating the particle size and structure of fine particles used in a liquid dispersion, it is common practice to dry the liquid to extract the fine particles as a powder and measure them using an electron microscope. However, this measurement method is not suitable for investigating how the particles are dispersed, as changes in the dispersion state and deformation of the particles can occur due to drying. In MST, to directly assess how fine particles are dispersed within a liquid sample, cryo-processing followed by SEM analysis (cryo-SEM analysis) is performed for evaluation.

Evaluation of the ionization potential of semiconductors

Evaluation of the ionization potential of semiconductors

UPS: Ultraviolet Photoelectron Spectroscopy

In semiconductors, it is possible to determine the ionization potential from the valence band maximum (VBM) and the rising position on the high binding energy side (Ek(min)). Measurements are conducted after Ar ion sputter cleaning to remove surface organic contamination. ■ Determination of the valence band maximum (VBM) The spectrum near the valence band edge is extrapolated linearly to find the intersection with the background. ■ Calculation of the ionization potential Ionization potential (I.P.) = hν - W hν: Energy of the incident ultraviolet light (He I line 21.22 eV) W: Energy width of the spectrum (Ek(min) - VBM)

[Analysis Case] Evaluation of Surface Deterioration of Polycarbonate

[Analysis Case] Evaluation of Surface Deterioration of Polycarbonate

Structural analysis of resin surface degradation using TOF-SIMS.

Polycarbonate (PC) is a type of thermoplastic that has excellent transparency, impact resistance, and heat resistance. It has been reported that degradation occurs due to hydrolysis, leading to the generation of the raw material bisphenol A (BPA). Particularly in solar panels, it is important to understand how the surface of the material changes under UV (ultraviolet) irradiation. Below, we present a case study that evaluated the degree of degradation of the PC surface due to UV irradiation using TOF-SIMS.

Valence evaluation of metal oxides by chemical shift

Valence evaluation of metal oxides by chemical shift

XPS: X-ray Photoelectron Spectroscopy

In XPS analysis, the binding state evaluation of the material surface is conducted by observing the energy of photoelectrons obtained through X-ray irradiation. It allows for the assessment of whether metal elements are in an oxidized state, and for elements with significant energy shifts (chemical shifts) due to oxidation, it also enables the evaluation of the presence and proportion of multiple valences. Below are the main metal elements and oxides for which multiple valence evaluations are possible.

Evaluation of the orientation angle of organic film materials

Evaluation of the orientation angle of organic film materials

XAFS: X-ray Absorption Fine Structure

Self-assembled monolayers (SAMs), which are oriented organic films, have their functions and properties, such as surface wettability and adsorption, altered by orientation and orientation angle. Using XAFS with synchrotron radiation, it is possible to evaluate the orientation and orientation angle of organic film materials by analyzing the X-ray incidence angle dependence of peak intensity.

[Analysis Case] Evaluation of Additives in Polymer Materials

[Analysis Case] Evaluation of Additives in Polymer Materials

Qualitative analysis of components by LC/MS.

Many additives, including plasticizers, are used in polymer materials such as resin products. We present a case study on the qualitative analysis of additives contained in commercially available PVC resin. The components eluted by immersion in an organic solvent were qualitatively analyzed using LC/MS. As a result, components estimated to be DEHP (DOP) as a plasticizer and epoxy fat (plasticizer/stabilizer) were detected. By using standard samples, it is also possible to quantify each detected additive component.
