The MST website has published analysis case studies. ◆Title Heating Degradation Test of Lithium-Ion Secondary Batteries ~Samples after heating degradation can be evaluated using LC/MS/MS, TOF-SIMS, TEM+EDX, etc.~ ◆Measurement and Processing Methods TOF-SIMS, TEM, LC/MS/MS, FIB, μ-sampling, lift-out, disassembly, atmosphere control ◆Product Field Secondary Batteries ◆Analysis Objectives Composition evaluation, identification, chemical bonding state evaluation, film thickness evaluation, degradation investigation, reliability evaluation ◆Overview The development of lithium-ion secondary batteries faces challenges such as performance enhancement, longevity, and reliability improvement. To address these challenges, understanding the degradation mechanisms of the batteries is crucial. In this instance, a heating degradation test was conducted to evaluate the degradation mechanisms due to temperature. After the heating degradation test, samples that showed significant capacity reduction were evaluated using LC/MS/MS for the electrolyte, TOF-SIMS for the anode surface, and FIB-TEM+EDX for the anode cross-section. ★★For detailed data, please refer to the link★★

The MST website has published analysis cases. ◆Title Gas Emission Analysis and Polymer Material Identification Using Pyrolysis GC/MS ~About the Principles and Applications of Pyrolysis GC/MS~ ◆Measurement Method / Processing Method GC/MS ◆Product Fields Lighting, Display, Cosmetics, Daily Necessities ◆Analysis Objectives Chemical Bond State Evaluation, Safety Testing, Thermal Property Evaluation ◆Overview Pyrolysis GC/MS is a gas chromatograph mass spectrometer equipped with a pyrolysis device in the sample introduction section. For polymer materials that previously required complex pretreatment, the sample can be heated using the pyrolysis device, allowing the gases generated to be introduced into the GC for analysis without pretreatment. Additionally, by varying the temperature conditions of the pyrolysis device and the sampling conditions (double-shot method), it is possible to obtain two different types of information separately, such as additives and polymer materials, from the same sample, making the analysis of unknown polymer materials easier. ★★For detailed data, please see the linked page★★

We have published analysis cases on the MST homepage. ◆Title Investigation of Curing Temperature and Glass Transition Temperature of Epoxy Resin ~Thermal Property Evaluation by DSC (Differential Scanning Calorimetry) Measurement~ ◆Measurement Method / Processing Method DSC ◆Product Field Electronic Components / Daily Necessities ◆Analysis Purpose Product Investigation / Thermal Property Evaluation ◆Overview Using DSC (Differential Scanning Calorimetry), we investigated the curing temperature and the glass transition temperature (Tg), which is an indicator of heat resistance, for a two-component epoxy resin. The DSC measurement of the uncured resin confirmed that a rapid exothermic reaction began around 103°C (Figure 1). This was due to the polymerization (curing) of the resin caused by the temperature increase. Furthermore, after air cooling the cured resin to room temperature, a second DSC measurement showed a shift of the baseline towards the endothermic side due to the glass transition of the resin, with Tg being approximately 116°C (Figure 2). ★★For detailed data, please see the linked page★★

We have published analysis cases on the MST homepage. ◆Title Evaluation of Bone Condition Before and After HF Treatment ~Evaluation of Condition Before and After Chemical Treatment Using Raman Analysis~ ◆Measurement Method / Processing Method Raman / Chemical Treatment ◆Product Field Pharmaceuticals / Biotechnology ◆Analysis Purpose Evaluation of Chemical Bonding State ◆Overview HF (hydrofluoric acid) is widely used in processes such as wet etching of SiO2 and plays a very important role in semiconductor manufacturing. However, it is also a very dangerous chemical that can penetrate the skin and damage bones, requiring careful handling. The erosion of bones caused by HF occurs due to the reaction between Ca, which exists in bones as apatite, and HF, resulting in the formation of CaF2. This case introduces an evaluation of the changes in this reaction using Raman analysis. ★★For detailed data, please see the link★★

We have added one analysis case to the MST homepage. ◆Title State Evaluation of Organic EL Device Materials ◆Measurement Method/Processing Method: TOF-SIMS; Processing under Controlled Atmosphere ◆Product Field: Display; Lighting ◆Analysis Purpose: Composition Evaluation; Identification ◆Overview: Organic EL devices have advantages such as high brightness, high-resolution color, and thinness due to their self-emission principle, making them one of the promising next-generation display devices. Accurate analysis and evaluation of materials are crucial for improving characteristics, extending lifespan, and enhancing reliability; however, care must be taken as very reactive materials are used. A comparison between samples exposed to the atmosphere and those handled under high-purity nitrogen atmosphere confirms that oxidation (parent ions +O, +OH, etc.) observed with atmospheric exposure is suppressed when handled in a high-purity nitrogen atmosphere.
