Differences between LDI-MS and MALDI-MS
LDI (Laser Desorption Ionization) is a method that uses only the energy of ultraviolet lasers to sublime and ionize molecules. On the other hand, MALDI (Matrix-Assisted Laser Desorption Ionization) is a method that sublimates and ionizes molecules by exposing a sample mixed with a matrix to ultraviolet lasers.

Infrared spectroscopy is a method for obtaining information about molecular structure by measuring the infrared absorption due to molecular vibrations.
O-PTIR has the following features: - It allows for spectral and image measurements in small areas due to its spatial resolution (maximum spatial resolution: less than 1μm). - No need for thin sectioning (effective for samples that are difficult to thin section, such as foreign materials). - Measurements can generally be performed non-destructively. - Similar analyses can be performed using the FT-IR library.

TOF-SIMS and MALDI-MS, which are representative mass spectrometry methods for solid sample surfaces, both enable qualitative analysis and imaging analysis. TOF-SIMS, which utilizes hard ionization methods, can detect inorganic and organic components with masses up to several hundred with high sensitivity. On the other hand, MALDI-MS, which employs soft ionization methods, can detect polymers in the range of thousands to tens of thousands. Additionally, the spatial resolution of the images also varies depending on the diameter of the irradiation beam.
Extraction of electrolyte from the product and component evaluation.
The characteristics and reliability of lithium-ion secondary batteries are greatly influenced by materials, among which the impact of the electrolyte is said to be significant. Commercial products in various shapes, such as cylindrical and laminated types, can have their electrolytes extracted using appropriate methods, allowing for the identification of organic solvents and additives. The following case involves extracts from prismatic batteries, confirming the use of ethylene carbonate (EC), ethyl methyl carbonate (EMC), and diethyl carbonate (DEC) as organic solvents, and fluoroethylene carbonate (FEC) as an additive.
The degree of imidization due to differences in heating conditions can be evaluated using XPS.
Polyimide has very high heat resistance and excellent electrical insulation and mechanical properties, making it an essential material not only for electronic components but also for a wide range of fields such as precision machinery, automobiles, and aerospace. In its reliability evaluation, research on imide bonds is important. This document presents an example of XPS measurements conducted on polyimide before and after heating. Changes in the amount of oxygen and the chemical shifts of carbon, nitrogen, and oxygen confirmed that imidization progressed after heating. Additionally, by performing waveform analysis, it is also possible to determine the proportion of polyimide present.

The segregation of components and the formation of films on the surface of the positive electrode of lithium-ion secondary batteries are factors that influence the electric capacity. We will introduce a case study on Li(NiCoMn)O2 (NCM), which is used as a positive electrode, where micro-region mapping was conducted using AES, and qualitative analysis of organic components (binder) and active material surface films was performed using XPS and TOF-SIMS. These methods allow for analysis with a series of treatments conducted under an Ar atmosphere, which helps to suppress the alteration of the sample.
Quantitative analysis of positive electrode active materials, precise evaluation of crystal structure.
In lithium-ion secondary batteries, Li(NiCoMn)O2 (NCM) used as the positive electrode can achieve higher capacity by increasing the Ni ratio, and it also excels in high-temperature storage, making it suitable for mass production for automotive applications. On the other hand, cation mixing, where Ni ions occupy Li sites, is considered one of the factors contributing to the degradation of secondary batteries. This presentation will introduce a case where the metal content of the positive electrode active material was evaluated using ICP-MS, the crystal structure was assessed using XRD, and the results were used to perform Rietveld analysis to evaluate the proportion of cation mixing.

Simultaneous measurement of inorganic and organic components in minute specific areas.
TOF-SIMS has features such as simultaneous evaluation of organic and inorganic materials, capability for micro-area analysis, and high sensitivity for analyzing the very surface, making it effective for residue investigation in cleaning processes. An example is presented where pure water was dried on a silicon wafer. Optical microscopy only reveals slight point-like foreign substances and cloudiness. However, the results measured by TOF-SIMS showed that in the contaminated areas, organic components such as hydrocarbons, PDMS, and amides, which tend to adsorb naturally, were aggregated.
Capable of evaluating three-dimensional structural changes according to tensile stress.
In situ X-ray CT measurements allow for internal structure analysis under conditions where a load (tension or compression) is applied to the sample. In this document, in situ X-ray CT measurements were conducted using an aluminum plate as the sample, both in its normal state and in an extended state. We calculated the tensile stress applied to the sample and monitored the internal structural changes under each stress condition. By combining in situ X-ray CT measurements with image analysis technology, it is possible to evaluate under actual usage conditions, which was previously difficult, and assess the impact of stress on the product.
It is possible to calculate the concentration of phosphorus-containing organic compounds using 31P nuclear magnetic resonance!
We offer NMR (Nuclear Magnetic Resonance Analysis) services. Since NMR directly observes nuclear spins, the area of the peaks of the measured nuclides obtained from the measurement is proportional to the number and concentration of the nuclides contained in the solution or solid being measured. Based on this principle, NMR allows for quantitative analysis without the need for a calibration curve. For example, using the integral value of the peak of the 31P nucleus, it is possible to determine the concentration of one component of a two-component mixture from the known concentration of the other component according to a relationship.

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.
